Can you just eliminate theem or plugin issues, this should show descriptions (content) on the category pages.

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, switch to a default theme such as twentytwelve, and see if this fixes.
