Hello again folks, I'm still fighting a battle with lost session data. It seems like I'm getting closer--I have my session.save_path in a custom php.ini file pointing correctly to a directory I have full access too, and I even see files being written there, but they are empty (0 bytes). The end result is I'm still not able to edit pages while logged in. Mediawiki continues to report a loss of the session data. Another php site we have on the same server space does show session data in it's session file, so I think it's something with the mediawiki configuration. The files being written are in the format "sess_lotsofrandomnumbersandletters" , and permissions are set to -re------ (600). Is that how they should look? Complete symptoms: I can only edit files if I'm NOT logged in. I can only upload files if I am logged in. I can only stay logged in while changing pages if I check the "Remember me on this computer" box while logging in. In other words, in appears that no session data is being saved on the server, and/or being retrieved, in spite of the session files being written in the directory specified. What else can I be missing that would be causing a continuous loss of session data? This is a fresh install of version 1.10.0 running under PHP Version 5.1.0RC1, The Server API is listed as CGI, if I am stating that correctly, and this is all running on Linux. I'm using a custom php.ini file I can teak to override the defaults. If it helps to figure out the issue, here is a link to pi.php file to see the environment: http://americanpipemakers.info/mediawiki/pi.php I'm a noob with all this. I love mediawiki, and think it's perfect for my application, but I obviously need to get this nailed down before I can launch the project. Thanks for trying to help, Scott
