Your PHP build is missing MySQL support.

PHP Fatal error: Uncaught Error: Call to undefined function mysqli_init()

You'll need to make sure PHP has support for the mysqli extension to ensure compatibility with XenForo.

 

[Abraham54]

I do not know what is missing in PHP 8.
See screenshot:

 

[Chris D]

The error suggests mysqli is missing. Your screenshot suggests it shouldn't be. This may be a more fundamental issue with the server or panel software.

Either way that is an issue that must be resolved before you can use XenForo.

We're not actually recommending customers upgrade to PHP 8.0 yet. It has been released only a week ago and there may be a number of fixes we still need to make in XenForo before it is ready. There may also be bugs in PHP 8.0 that may not get fixed until a future version.

 

[Abraham54]

Well Chriss, thank you for your detailed answer, now I understand it and will wait for further improvements in the next version release.

 

[Nicolas FR]

In addition to the changes listed below, 2.2.2 has some invisible changes to improve performance, stability and compatibility with the newly released PHP 8, which we look forward to supporting fully in future.

We're not actually recommending customers upgrade to PHP 8.0 yet.

There may be something to clarify here to avoid this kind of inconvenience to users ?

 

[Chris D]

We didn't recommend customers upgrade to PHP 8.0.

 

[Nicolas FR]

That's true but this stability and compatibility with the newly released PHP 8 may suggest otherwise, in my mind.
And as you can see some users tried to upgragde to PHP 8.

 

[Chris D]

Well, it doesn't. It just says that we improved stability and compatibility, which we did, and "we look forward to supporting [PHP 8.0] fully in future", suggesting that it may not currently be fully supported.

Even so, PHP being built without MySQL support isn't something we have any control over.

Besides all of this, isn't it just common sense? Why would anyone want to risk upgrading core server software on a production server without fully testing for compatibility or without a reasonable period of waiting to ensure any kinks in the new version have been ironed out?

Even when we've caught any compatibility issues in XF, there's nothing to suggest that there won't be add-ons that have breaking compatibility issues.

 

[Nicolas FR]

I understand...
But maybe you have a responsability somewhere with your customers : if some of your customers cross the road without looking and get run over, do you just have to say "they lack common sense" or maybe it's better to think that they actually lack common sense but as they are my customers I'll put a sign: "look before crossing".
Sorry for the off-topic but i think it's important and as I do not have much common sense in this matter I am only saved because my host does not offer the upgrade to PHP 8.

Where is the problem? XenForo does not currently state to support PHP 8 (PHP 7.4 is currently state of the art) and if users use PHP8 on their own they are responsible for it.

I'm in PHP 8 after some addon fixes and that: https://xenforo.com/community/threads/push-notification-classes-errors-after-php-8-0-upgrade.188515/, no errors now but its easy that you need to deal with some inconveniences to get fully working.
