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.
