Upgrade to PHP 8.x gives error 500
Posted: Thu Dec 22, 2022 4:47 pm
When I upgrade PHP from 7.4 to 8.0 or higher, both frontend and backend pages are blank with a message "HTTP error 500".
I have FTP access to the files, so I can delete cache or upload files if needed. I can also change PHP back to 7.4 and access the site like before and change settings in admin panel.
In mid January my ISP will no longer support that version, so I am in a bit of a hurry...
The CMSMS version is 2.2.8.
Any help will be greatly appreciated
When I turn on PHP error messages, this list below is shown, but I don't understand what the messages mean, or what I have to do.
