Errr....so, having installed MU#40 for Plesk 10.4.4 a few days ago and having updated php at the same time on a particular system, I received a call from a customer who is using php-fastcgi to say that there were errors relating to saving session files in his website logs.
To my amazement, I found /var/lib/php/sessions to be root.apache drwxrwx--- just as it should be.
What's more, I never got round to fixing the ownership and permissions on this particular system.
So SOMETHING has automagically fixed the ownership and permissions issue.
But it doesn't explain why the customer is seeing session write errors. I thought this was dealt with autmagically by Plesk when php-fastcgi was used. Ah well. One thing fixed, another broken
QUICK UPDATE: It must be ASL - Scott/Mike have added something without telling us? I've checked 4 systems. 3 ASL ones have correct ownership/perms. One non-ASL one has wrong perms/ownership.
