Unknown column 'c.ID_CAT' in 'on clause'

[monizist]

hello,

when trying to view messages by clicking at the forum index-page i get the following message:
'Database Error
Please try again. If you come back to this error screen, report the error to an administrator.'

after login and checking the forum error log, i found this:

hxxp:www.musicker.net/musickerforum.jpg [nonactive]

about 55 error-templates - and i always wondered why so few people are writing...now i know why...;¬(

also, from the error log template i cannot accesss the index-page anymore:
'database error: Unknown column 'c.ID_CAT' in 'on clause'
File: /data/members/paid/m/u/musicker.net/htdocs/www/forum/Sources/BoardIndex.php
Line: 83'

this was with firefox 1.0.7. - same with opera 9...

can you help?

thx,

greg
