How to prevent this in future:
1. Consider converting your forum tables from MyISAM to InnoDB - InnoDB is much more crash-resistant and recovers automatically after unclean shutdowns
2. Set up a regular MySQL backup so you always have a clean copy to restore from
3. You can add a weekly repair job by adding to cron:
About item 1, is this possible to do with a UBBthreads forum?
from MyISAM to InnoDB or is the forum software programmed to use MyISAM only?
As you know I don't much about this..😅
