Version of phpBB3: 3.0.0
Was this a fresh install or a(n) update/upgrade/conversion (please be specific)? phpBB 2.0.22 -> RC2 -> [all RCs] -> 3.0.0
Was this an install through your host? No
When the problem started: A few hours ago (this night GMT time)
When I visited the forums this morning, I got the following "General Error" message:
I went to phpMyAdmin, repaired the table, but instead of getting the status "OK" or something similar, it said "Table is already up to date". When I visited the forums again, the error message was slightly different:Table 'phpbb_sessions' is marked as crashed and should be repaired 
I've tried repairing several times, but I always get the status "Table is already up to date" and the table obviously cannot be reapired. I've also tried using the file posted here, but it seems to run the same SQL command and doesn't work.Table './globalrs_community/phpbb_sessions' is marked as crashed and should be repaired 
I have shell access to the server.
Does somebody know hwo to fix this?
