For some reason, overnight (I didn't change anything), my forum seems "broken." When you visit the homepage you get a message that says:

----

Script: /forums/scripts/cfrm.inc.php
Line#: 180
SQL Error: Can't open file: 'ubbt_ONLINE.MYI' (errno: 145)
SQL Error #: 1016
Query: SELECT ONLINE_BROWSING_FORUM,COUNT(*),ONLINE_USER_TYPE FROM ubbt_ONLINE WHERE ONLINE_LAST_ACTIVITY > 1217499456 GROUP BY ONLINE_BROWSING_FORUM,ONLINE_USER_TYPE

Please use your back button to return to the previous page.

Can someone please help me fix this? I did not change a thing, so I wonder if it is a server-side issue? HELP!

Thanks

Bryan
