A bunch of WordPress sites broke without any errors and without that usual “Your site is experiencing technical difficulties” notification. The sites were only displaying a blank White Screen Of Death.

Enabling wp_debug didn’t show anything at all, which is pretty unusual. But in the error log I found Failed opening required '/home/user/public_html/wp-content/advanced-headers.php which is just as it sounds, there is a file that must be included but it couldn’t be opened.

In fact the file is completely missing in each case. I think the error is being caused by some sort of issue with the Really Simple SSL plugin, I remember spotting something about it, but can’t find it again.

No worries, the fix is trivial. Simply create an empty file named advanced-headers.php in the /wp-content directory. I am not sure what the original contents were or what it is supposed to do, but at least this gets the site up again.

Here’s a cautionary tale. All the customers who subscribe to the WordPress Management Thingy had this spotted and then fixed (for free, of course) because it showed up in my management dashboard. Cheap insurance I reckon. Just saying ;o)

One of the ways to determine if an email is genuine or not is to inspect the headers.

4 October, 2023 – modified from original source: https://www.auda.org.au/blog/starting-business-six-au-domain-name-tips-new-businesses

When you start a business, a carefully thought-out digital presence can help you get ahead. Ninety-nine per cent of Australian adults use the internet, so a business website and email address with a professional, easy-to-remember domain name will help you to reach a broad audience and connect to your potential customers. 

Below we set out six tips for selecting a domain name to set your business up for success. 

1.    Choose a memorable domain name relevant to your business 

A domain name is your digital address and a key element of your brand identity. Choose a domain name that: 

• Reflects your business name or services – this helps build brand recognition and makes it easier for people to find your website when searching online. 
• Is short and simple – this makes it easier for customers to remember and type your domain name into a web browser. As a guide, aim for 15 characters or less. 
• Avoid hyphens, numbers and symbols – these can be difficult to remember, misinterpreted if received verbally and mistaken for illegitimate websites. If you must use a number, use its written form i.e. “two”, instead of “2”. 
• Passes the “radio test” – this is a simple way you can test the effectiveness of your domain name. Say the name to five people and get them to write it down. If they don’t get it right, consider a domain name that’s simpler to convey. 

2.    Consider .au for a trusted option

Australians choose .au because it’s local, trusted and secure. Research shows three out of four Australians trust a website that ends in .au. Half of Australian consumers say they will only shop on websites that end in .au. Given its popularity among consumers, it shouldn’t be surprising that three of four Australian small businesses choose .au as the primary domain for their websites. As an Australian business without a .au domain name, you may be missing out on a large segment of the market. 

There are a number of .au namespace options available. The com.au namespace is dedicated to businesses registered to trade in Australia. This a good option for existing small and medium businesses. For entrepreneurs (or those still dreaming up their big idea!) .au direct is a great choice. It’s a short, simple, uniquely Australian option that is available to businesses as well as individuals and organisations. 

3.    Check the domain name you want is available and doesn’t infringe on a trade mark

When you’ve decided on a domain name you’d like to register, check if it’s available via the ‘find a domain name’ tool on the auDA website. If your preferred domain name isn’t available, choose another option, keeping in mind our tips at point 1 above. 

It’s also a good idea to check whether there may be any trade mark issues associated with your desired domain name. Conduct a trade mark search to check if the domain name you’d like to register is registered as a trade mark in Australia. If it is, we suggest you seek legal advice or select an alternate domain name.

4.    Register your domain name when you set up your business

Registering a business on the Australian Business Registration Service does not mean you automatically access a corresponding domain name. .au domain names are licensed through 123Host as a separate process. Although separate, we recommended you complete these steps at the same time to ensure you’re able to register a business and domain name that complement each other. 

If you are planning a complementary social media presence, it’s also worth checking your preferred social media handle is available to secure the digital identity of your brand. 

Even if you don’t intend to build a website right away, registering a domain name means it will be available when it’s time to launch your website or business email address. 

5.    Set a reminder to renew your domain name to prevent it from expiring 

.au domain name licenses are not granted indefinitely, but for a period of one to five years. You must renew your domain name license before it expires to continue using it. .au domain names can be renewed 90 days prior to the licence expiry date. Your registrar will send you a reminder email as the end of your licence period approaches.

Keep your contact information up to date to ensure you receive these emails. If your .au domain name licence expires before you renew it, you’ll have a 30-day grace period in which to renew your licence. Some registrars may charge a fee to retrieve an expired licence within the grace period. If you don’t renew it within the grace period, the domain name will become available to be registered by the public on a first-come, first-served basis. 

You can check your .au domain name licence expiry date and contact details with the auDA password tool.

6.    Do your domain name due diligence when buying an existing business 

If you become the new owner of an existing business and you plan to use the domain name associated with that business, you must have the domain name licence transferred to you. The transfer of a domain name is not a process that occurs automatically with the sale of a business. If the domain name is not transferred, there can be disruption to the business’ website and/or email services. 

Much like transferring the registration of a car, it is a joint responsibility for both parties to approve the domain name licence transfer. Learn more about transferring a domain name when buying or selling a business. 

Friday Afternoon

There have been a few ongoing niggles that are being sorted as people discover them. If you are seeing this when you try to send in gmail…

get in touch. It seems that google has lost the connection to your outgoing mail server, it is a very easy fix.

Friday Morning

Well, the migration finished and now the resource graphs look like this, with everything settling down :o)

If you haven’t already, please CHECK YOUR WEBSITE. There have been a couple of instances where some things didn’t migrate properly. They are fixed really quickly, but I have to know about it.

Over the next week there will still be some fine tuning. There are a bunch of things that are different and some new things. But that is for another post to keep separate from the migration story.

Thursday 2145PM (AEST)

To the handful of people suffering a bit of pain, please be patient. The migration is at 75% and should be completed within a couple of hours. Meanwhile it is a balance between going hard to get it done quickly or stretching it out and reducing pain for some but increasing it for others.

The server is running hard at the moment – the graphs flatten because certain things like RAM usage reach a specified limit to prevent everything bogging down.

I am going to post the comparison in the morning.

Thursday 1400PM (AEST)

We have just successfully tested the first migrations. Happy Dancing here so far!

Because the old server and new server are in the same data centre, transfers are lightning fast, it will still take some time to do them all (there are a lot of accounts).

The majority of sites should be on the new server by about 1630, the bigger sites which we are leaving until last will take until about 2230.

Thursday 1230PM (AEST)

If you read my earlier post you will have an understanding of what has been happening. The migration to a new server will happen this afternoon and into the evening, it will take quite a while. There should be no downtime for any sites, but as with any technology, what could possibly go wrong?

I’ve asked them to keep me informed about the progress and I am going to update this page as often as I can.

Some people will need to be contacted to update settings, but even those sites will continue working, it is just something that will need to be done within the next couple of weeks.

IF YOUR SITE WAS WORKING AND YOU SUDDENLY NOTICE IT ISN’T, EMAIL ME but I have been assured “we have done this thousands of times and it should be fine” – what can I do except trust them/

The outcome of all this should be a stable, faster server and a more chilled Steve.

I appreciate your patience up until now. If you have any questions, fire away.

Thursday 10:30AM (AEST)

If you are a 123host customer you will know that the server has been pretty unreliable for the last week or so. There has been a bunch of brief outages and a couple of extended outages. Some of you will know because you have spotted the problem, others know from the email I sent out. Whichever you group are in, I sincerely apologise for this and offer the following without it being any way a lessening of my responsibility.

Something is going on. Between me (with help from a fellow web host), the server provider and cPanel (the operating system developers) we have spent a lot of time trying to diagnose what is going on, so far without success. What they say is happening (and I don’t necessarily agree) is that there are too many accounts on the machine and at times it runs out of memory. An inbuilt safety system then shuts down some processes to bring things back under control.

Think of it as though you are driving at night and your car battery is a little low because you have too many electrical things running, suddenly your headlights (=the website software) stop working, but your car (=the server) is still running. Your car has some smarts and it turns off the radio and some other devices (=some running processes), then turns the headlights back on again and away you go – that is a near enough metaphor. But sometimes, for some reason, it doesn’t automatically turn the headlights back on, you have top lift the bonnet and flick a switch manually.

I can’t tell you how stressful this has been. I really try to deliver up to (in excess of?) my own expectations of services I receive and this is below that.

So after probing and thinking and eventually biting the bullet, 123Host will be moving to a much more powerful server at a new provider. This isn’t through any dissatisfaction with the old one, I have been there for a number of years and am mostly happy. But they are changing the model of how they provide servers so that in future I have to manage everything – software licenses, account backups, tech fixes etc. This will mean a lot more work for me, some of it beyond my skills. I would rather pay a bit more and have people who know this stuff do the stuff I don’t know.

I am waiting for a report from the new provider after they had a poke around in the server overnight. I anticipate that over the next week all sites will migrate to the new server. For most of you it will be transparent and painless. I will have to contact a few people to update some settings, but there is no urgency, everything will keep working.

That’s all for now. I will keep updating here as I know stuff.

October 22nd

You may have noticed that there have been several server outages over the last few days resulting in sites not being reachable.  Firstly I sincerely apologise for this, obviously it is not part of the grand plan.

In tandem with the data centre, I am working hard to determine the underlying cause.  The problem is that when everything is working, there is nothing to see.  It is trying to investigate at the very moment when a glitch is taking place, but we haven’t even figured out what is triggering it yet.

What I want you to know is that I am fully aware it is happening and that we are doing everything possible to get it fixed as a matter of urgency. 

I will update this post with what I know as regularly as I can.  If you have any questions email me, support@ – as usual I will be as honest and transparent as I can.

[UPDATE]
I haven’t been smiling much today, but the data centre replied and the jargon filled explanation put a wry smile on my face

We have fully reviewed all logs and from what we can tell the kernel is killing processes due to out-of-memory errors. The majority of RAM is being used as a cache for the database.

We have modified some settings to reduce normal system RAM usage and also reduced how aggressive the oom killer is.

It makes sense to me, but am thinking of offering a prize to the first customer to decipher it :o)

---

[LATER UPDATE]

The data centre hasn’t been able to solve this yet, so they have escalated it to cPanel, the developers of the server software.
