Hi, I have been having problems with blank pages showing up on the webmail (Horde). I have searched the forums, horde mailling lists etc with no clear fix for this. I have turned error reporting on via php.ini and the only error ever being reported is the PHP Fatal error: session_start(): Failed to initialize storage module: user error. I have since encountering these blank pages recompiled PHP from source and reinstalled it. When I restart httpd - the problem seems to go away for approximately 10 minutes or so then it reappears. In general when clients and myself get the blank pages error_log and psa-horde.log shows no errors. When I refresh (CTRL F5) approximately 5 times I get the horde login screen up - and a error is logged in error_log; PHP Warning: Unknown(): A session is active. You cannot change the session module's ini settings at this time. in Unknown on line 0 PHP Fatal error: session_start(): Failed to initialize storage module: user (path: /var/lib/php/session) in /usr/share/psa-horde/test.php on line 14 Anyone else experiecing these errors? This is only happening on one 7.5.4 server. php.ini session.save_handler = files session.save_path = /var/lib/php/session Am I missing something obvious? Any pointers/comments appreciated.
