Why am I getting a 'session_start()' error?

If you are seeing errors regarding the session_start() function or the $_SESSION variable, chances are you have a configuration problem.

The most common problem is with the PHP 'tmp' (temp) directory. Make sure the path to the 'tmp' directory in php.ini is correct and that there is indeed a folder at that location.
