PHP 8.0 or 8.1 with SuiteCRM 8.5

English Language - Forum

I recently installed SuiteCRM on InMotion hosting using Softaculous. If I use MultiPHP Manager to assign PHP 8.0 to this install, CRM loads. If I change it to PHP 8.1, it gives me the error below.

Problem is, with PHP 8.0 I’m getting logged out of CRM every minute or so and it’s not saving my changes if I don’t save before getting kicked out. I did research and this behavior has been related to PHP 8.0 (and the recommendation of moving to 8.1). So I’m stuck… any ideas?

It has to be 8.1:

Make sure you turn off display_errors in your php.ini, this will stop error messages from appearing on screen.

Then the other problem - frequent log outs - you have to deal with it separately. There are threads in these forums with similar issues. There could be many causes, especially on new installs.

You might want to check that your PHP session directory exists and is writable by the web server.
