Hi,
My XOOPS website stopped working when PHP was upgraded lately to 5 version with a "Fatal error: Unknown: Cannot find save handler files in Unknown on line 0"
Just for anyone interested I solved it by editiing mainfile.php and adding:
ini_set('session.save_handler', 'files');
ini_set('session.save_path', '/home/username/tmp/');
And the most important, set NO in persistent connection.
// Use persistent connection? (Yes=1 No=0)
// Default is 'Yes'. Choose 'Yes' if you are unsure.
define('XOOPS_DB_PCONNECT', 0);
Hope this helps anybody.
Cheers.
