odd error :S

[rob01]

hello, today i was trying to edit some of my posts, but i keep getting this error
"this forum cannot contain threads or it is a link please choose another forum", someone know what could be the cause of this error?

even if i make a new post, i will get this error, (if i use a website link)

:S any idea?

Check your forum settings in the AdminCP, and make sure you've marked the forum as open.
