Having this problem or one like it?
WordPress database error: [Can't open file: 'wp_stattraq.MYI'. (errno: 145)]
In case you’re wondering how to fix this situation, just go to your MySQL control panel (in my case, a cPanel), click on MySQL then on the Repair button next to the database’s name. Has worked like a charm for me on a number of sites where the database had gotten corrupted.
