I am getting this error message: Can't open file: 'tablename.MYI' (errno: 145)
If you are receiving this error you have a corrupted table in your database. Follow these steps:
1. Open phpMyadmin (select the MySQL icon in cPanel, phpmyadmin is at the bottom of the page);
2. Select the database that has the corrupted table
3. Select "SQL" from the main menu.
4. Type this query in the query box: REPAIR TABLE tablename.
For example, if your mt_linkwos table is corrupted run the query "REPAIR TABLE mt_linkwos."
