I repaired two of the three affected tables from the command line using:
sudo myisamchk -r /var/lib/mysql/wordpress/wp_wfBlockedIPLog
sudo myisamchk -r /var/lib/mysql/wordpress/wp_wfHits
Oddly, I couldn’t repair the third one as I kept getting the error that the file doesn’t exist, even though it does and has exactly the same owner and permissions as the other tables:
sudo myisamchk -r /var/lib/mysql/wordpress/wordpress/wp_wfLogins
