If you're running software that suddenly stops working, one troubleshooting step you can take is repairing your database. Bear in mind that this is just one of many troubleshooting steps you can take, but if you've exhausted all other options, you can give this one a shot.

Repairing Databases within cPanel

1. Log into cPanel
2. Click "MySQL Databases"
3. Under "Modify Databases", select your desired database from the drop down and click "Check DB"
4. If any errors are shown, return to the previous screen and this time run the "Repair DB" option (instead of "Check DB")

Repairing Databases within phpMyAdmin

You can also repair databases directly within phpMyAdmin. To do this:

1. Log into cPanel
2. Click "phpMyAdmin"
3. Choose the desired database in the left menu
4. Select all the tables listed by clicking "Check All" (see screenshot)
5. From the drop down menu choose Repair Table
