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 can not access your AdminCP, then you can upload the tools.php file from the vbulletin .zip file do_not_upload/ folder into your forumdir/admincp/ directory and run it through the browser, there's a switch there to run optimize and repair. Run it a few times for best result.

If you cannot access either the Admin CP or tools.php you can also use a tool like phpMyAdmin to repair tables.

If this doesn't help, please contact your host.
