I originally posted this in another thread, but thought it might help to start it in a new thread so I can at least help others see how to fix... or kinda fix. my forum went down and generated a "unavailable message". my host InMotion did a SQL repair, but was unable to get me back up. I went into my cpanel and truncated the xf_session table and the forum came back up. I'm still trying to figure out what caused this problem... any suggestions appreciated.
