I think I\'m having problems using PHP sessions because I\'ve got cPanel installed on the same server and I believe it has additional security in place that prevents write acces
/tmp should always be accessible. You can of course create a new "tmp" folder somewhere near you application. Just make sure it does not reside within the web root. Give it read/write permissions and chown it to the user of the webserver.
You then need to change the session_save_path to your new "tmp" folder.
