Blank page when upgrading PHP version

[Chuck Passaro]

Hello,

We run a dedicated server with two Invision Community installs. The PHP version currently running is 7.3 which is deprecated. For the new upgrade, I need to change this to at least 7.4, although I also have access to PHP8.0.

My problem starts when I change the version in WHM Multi-PHP Manager. I checked with main Invision install and the screen goes white. I tried disabling applications in Invision, with no luck. I then tried the other Invision installation and the same occurs there. 

Is there somewhere I could check to see what is causing this problem? Please bear in mind that I only know the very basics and would need an easy to understand explanation 🤣

Thanks,

Jim

Have you checked the requirement checker in the first instance? You can find this here

Hi Marc,

That file is already installed and just tells me I'm ready to install Invision 4.1 with zero problems. 

[Marc]

Do you have the latest version of that file? I ask, especially as you stated there "4.1"

[Chuck Passaro]

I do now. My apologies. 

This is the page report when I run it:

Indeed you would need then to update your PHP version. It seems its not being updated to the version you believe it is there

[Chuck Passaro]

No, that's not the problem. I can change the PHP version in WHM, but when I do, I end up with a blank white page instead of the forum. This happens on both forums on same dedicated server.

Please switch to that version, then let me know so I can take a look. The message there however would indicate you are not actually using PHP 8

This you would also need to contact your hosting company about, as you are missing requirements

Thank you very much. Onto them right now.

Hi, I'm facing a similar problem and everything looks good on PHP 8.0: https://d.pr/i/z707Ug

I can browse the Admin, plus my forums' homepage and forums, but not any topic. Blank pages all the time.

Checked the logs and found this, don't know if it's related:

[12-Jul-2022 08:49:24 UTC] PHP Fatal error:  Declaration of IPS\Theme\Cache\hook93::topic($topic, $comments, $question, $votes, $nextUnread, $pagination, $topicVotes = []) must be compatible with IPS\Theme\Cache\class_forums_front_topics::topic($topic, $comments, $question = null, $votes = [], $nextUnread = null, $pagination = null, $topicVotes = []) in /home/macmagazine/forum/system/Theme/Theme.php(951) : eval()'d code on line 7

Any help, please?

You're right. I tried disabling an application before, but forgot about the plugins' area. Thanks!

No problem at all. Glad to see you sorted the issue 🙂
