Hello,

Can-you put here your kunena report configuration settings ?

Can-you look into your phpinfo, if you see something about cache system ?

Dejavu.. Did I already answer to similar issue?

This looks like database corruption -- you are probably using MyISAM tables and your server got power outage while it was writing to MySQL tables.

Whatever the reason was -- files got badly corrupted. You MIGHT be able to recover them by fixing the tables, but it's also likely that the files are beyond repair.

If you haven't resolved this issue, please contact your service provider and ask for backups.
