If this is phpBB, did you check the cookie timeout? The couple I run for various boards as a time in milleseconds you can adjust. I might be confusing it with SMF or VB, but I think it is either in general configuration in the admin or it is a manual edit of the configuration file itself. Just thoughts. Don't quote me on it, because until I am actually in the code doing a setup, specific knowledge just vanishes into a sealed archive in my
ain.
