Database Error

[Spikey_IT]

The Forum is not available and the database gives me an error that the smf_log_online table is marked as crashed and should be repaired. I used the repair option and it said it was repaired successfully but the error remains. The version of the SMF is 2.0.15.
Any help on how to fix this and what might cause the problem is appreciated.

Backup then I would repair it via SSH command prompt and not PHPMyadmin.
