We've been running osCommerce website flawlessly for over two years, but recently encountered the following MySQL error.
1016: Can't open file: 'user_tracking.MYD'. (errno: 145)
We're running mysql 3.23.58 version, and recently restarted the mysqld by killing the mysql processes. This may have corrupted the table file named above.
You may use phpMyAdmin to "repair" the corrupted table. Or, use the command line from the mysql client.
