I'm getting the following error:
PHP Warning: session_start() [<a href='function.session-start'>function.session-start</a>]: open(/tmp/sess_49a20cbe1ef09a2d0262b3f7eb842e7b, O_RDWR) failed: Permission denied (13) in /home/------/public_html/includes/libs/ss.inc.php on line 1
The problem doesn't happen all the time, but comes and goes.
This the code at line on 1 in ss.inc.php
<?php session_start(); ?>
How to fix it?
