I'm getting a sql error when I try to login or run cron.php. Warning: Can't open file: 'watchdog.MYI' (errno: 145) query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (0, 'php', 'Can't open file: 'watchdog.MYI' (errno: 145)\nquery: DELETE FROM watchdog WHERE timestamp < 1149702748 in /includes/database.mysql.inc on line 120.', 2, '', '/cron.php', '', 1150307548) in /includes/database.mysql.inc on line 120Is this a MySQL server error? Has anybody else run into this problem? Site is live and has been running fine using 4.7.2. I've also sent a request to my host to have them look into it.
