I am having a similar problem to abujenin:
But mine are more like this:
Warning: session_start(): open(/tmp/sess_3e3ad2a88908ad325007c8011779c8dd, O_RDWR) failed: Permission denied (13) in /home/coreysm/public_html/squirrelmail/functions/global.php on line 295

I have been working on this for a couple of days now and I have uploaded and deleted over and over again with no success.
I have created my config.php several times, still without success.
Any help anyone could provide I would greatly appreciate.
EDIT: I figured it out - closing firefox and reopening made the errors go away.
