Hello,

I just had my webaster to enable PHP 8 for the community. We got an error 500 after that. 

We enabled 8.0 for WordPress and another domain in the same server and all went smoothly. It didn't work on Invision Community. We've reversed the installation to the previous php version and works fine again. 

I need help on this. 

Thanks

Where should I check exactly for these errors?

1. Error logs
2. System logs

Error logs report. These errors are not recent, they are the last ones from more than a month ago. Some plugins that may have not been updated to 4.7 yet and are running in the system

How do I know which third party plugin is the one not working according to the error logs? When I click on ERROR URL, ACP will not tell me which plugin it is 😞 Shouldn't it say at least tell us which one it is?

The URL does not give me a clue, I can see a file ID but how do I know which plugin it is? 

admin/?app=core&module=marketplace&controller=marketplace&do=viewFile&id=9784

Shouldn't the error show the plugin name that is giving the error and be more user-friendly? ACP knows the file ID is 9784, so shouldn't it be easy to show an error with the exact plugin name. Right now, I just don't know which one it is. File 9784. Who knows!

Thanks a lot

Hello I have same problem here, but for new installation, not upgrade

During installation process at the last step, progress bar is going fine and suddenly showing error 500 with any other info (see attached photo).

Then I've looked into error_log in the install folder and I've seen this

thrown in /home/arenagro/public_html/forum/system/Settings/Settings.php on line 180
[20-Aug-2022 01:35:39 UTC] PHP Fatal error:  Uncaught TypeError: array_merge(): Argument #2 must be of type array, null given in /home/arenagro/public_html/forum/system/Settings/Settings.php:180

#3 [internal function]: IPS\IPS::exceptionHandler(Object(TypeError))

Can you please help?

Thanks

 

EDIT: Strange. This error happened with PHP 8.0 or 8.1

After I put 7.4 for the domain, installation went well. It is ok with 7.4? Or should I do something differrent? Thanks again

Same problem from my side, I had to get back to PHP 7.4. Have you solved this? And if so, how?

Thanks!

 

Don't believe we ever heard back from you about what error is being generated from that 500 Internal Server Error in your server's error log. That would certainly outline an issue.

The problem for me was that with PHP 8.0 I was not able to open the website AT ALL, so I could not even enter the AdminCP to search for the error logs.
