To fix this run Repair/Optimize in the Admin CP. You may need to run it more than once to fix all errors:

Admin CP -> Maintenance -> Repair/Optimize Tables -> Check All -> Continue

If you cannot access the Admin CP you can also use phpMyAdmin to repair tables.

Also please see these instructions for other available methods to repair a database:

THANKS that worked but for some reason all my thumbnails for pics are not showing and I get error message, i ran the thumbnail cycle from the admin panel but it did not work at all. I get this message when I click the link that is in place of the thumbnail now

Warning: fopen(/home5/gixxerpl/public_html/images/attachments/2/5/0/2/2175.attach) [function.fopen]: failed to open stream: No such file or directory in [path]/attachment.php on line 261I noticed that home5 is not even my forum name it is home. I dont understand how these errors came to be when it was working fine. I attached a pic showing the error when I try to upload a pic now and how all the thumbnails look.
