PHP has an error similar to the following:

Warning: session_start () [function.session-start]:. Failed: No such file or directory. Wait for the situation

You can try to change the session.auto_start = 0 to session.auto_start = 1 in the php.ini file.

That is, the session variable requires temporary file space for the system and read and write permissions.
