Error 500 after upgrade of OJS to latest version

After an upgrade of OJS to the most recent version, the server returns an ERROR 500. PHP was upgraded to php8.1

I do not have full access to the website and version # at this stage, but this cannot be an isolated incident.

Any help greatly appreciated.

Hi @Andrew_Lian,

For the 500 Errors, it is best to check your PHP error log as that provides more clues as to what is going on - are you able to report on errors found there?
