I posted this in the old support forum and I’m still waiting for the fix.
With rtMedia Pro it is possible to enable attachments for bbPress. I’ve attached an image to a forum thread. It is still possible to access the attachment even after the thread has been deleted. Please fix it so that the attachments are deleted when the thread is deleted.
