Try going into phpMyAdmin from your Web host control panel

  • click on Databases
  • click on the database your forum is using
  • go to the very bottom of the page and you should see an option to check all tables.
  • Click CHECK ALL and that should place a check mark on all the tables.
  • Then once again go to the bottom of the page and select in the dropdown box REPAIR TABLE
  • It will then work on repairing them if there is an issue.
  • Then go back and run the OPTIMIZE TABLE command


Then try to connect to your forums and see if you're still having the same issue.
