It could be a theme or plugin issue
Plugins
Deactivate all but bbpress and see if this fixes. if it does, re-enable one at a time to see which is causing the error.
Themes
If plugins don’t pinpoint the problem, as a test switch to a default theme such as twentytwelve, and see if this fixes.
So it doesn’t seem to be a plugin or a theme caused error sadly. I have no idea.
@jaydd
was bbPress working fine for awhile then this error came out of nowhere??
did this error come after you imported forums into bbPress??
do you have a large number of topics/replies??
have you followed these two guides for developing your child theme for bbPress??

are your permalinks set to post-name??
also could you paste an example url of the original topic url and the url you get when you have a 404 error.
Hello! Using bbpress repair tool somehow made it work. Tho a week ago it didnt, i like these kind of problems^^
@jaydd
