The latest update to Blackboard has produced a bug that will cause an “Access Denied” error message to instructors trying to access a Discussion Board Forum that is set to unavailable. The error occurs either when you click on the Forum Name or Open from the options menu. Blackboard recognizes this as a Known Issue and is currently working on a patch to fix the error.
The current resolution or workaround is to set the forum to available. The options to grade, edit, or read unread posts still work and are not affected by this bug.
