PHP Fatal error: Unable to start session mm module in Unknown on line 0
"PHP Fatal error: Unable to start session mm module in Unknown on line 0"
when attempting to start apache with php4 on debian stable, testing, and
possibly others.
It's a fairly cryptic error message several people have complained about
on a few lists including this one, and theres no good answers posted
anywhere for the most obvious cause, so I'm posting this, having just
encountered it:
There are a lot of suggestions involving changing the shared memory
size, and deleting session files, however I found this to be the error
message you get when the session directory does not exist. This may
often occur when its defined as /tmp/phpsess, and a reboot cleaned all
the files out of /tmp.
Simply mkdir /tmp/phpsess or whatever the directory is set to in your
php.ini
hope this is helpful to someone.
