Thanks for the reply. The ubbt_PORTAL_BOXES table is still messed up, in mysqladmin it says 'in use' and the browse,search, and empty actions are disabled. The structure and insert actions come up with the 'incorrect file format' message. When logging on to the forum you can get on now by refreshing the screen when the error message appears. I don't have any custom islands, in the control panel all the portal selections come up with an error message. What course should I take to repair this??
