PHP site suddenly not working properly!

One of my sites has suddenly stopped working properly and I think the latest update to CWP caused it. when users try to log in it just loops back to sign-on

I figured it out! and YES it was caused by a CWP update that added a session save path to the php.ini which my site didn't use and didn't have one defined.  I checked other sites I host and found the same in their php.ini files.

Hey CWP when you do updates and change things to make them compliant with higher php versions a little popup or notification of what might get changed or simply keeping site's ini files the same unless admin changes them!

TY
