I have set up 2 server setup and all looks and works ok, except for Roundcube. I have checked the logs and do not have any errors. 2 accounts have been set up, and I had successfully logged in once, but not since. My observation is that I get a successful login as I get by the login page, and see the users Roundcube screen. I then get a message in the middle of the screen stating I have a invalid or expired session. Then back to the log in screen. I have search for 4 days on different solutions. Time Zones, Time Out, use_https, force_https, time difference between servers, mysql is on a separate server. I have deleted my session cookies in my browser, and removed the sessions from mysql. Is there any solution for this error? This is the first time I have installed Roundcube, usually I use SqirrelMail, can I replace Roundcube with SquirrelMail? Can they both be installed as long as I don't provide a /webmail alias?
