I have the same problem. Any solution to this?
BbPress Version 2.5.8 is the best. I am using it!
I use the absolute newest version of WP and 4.4.2 and can’t upload images directly in the editor and didn’t find a plugin for doing it (uploading, display them inline etc.)
I have tested your code. Well I can select in the admin panel “edit topic” or “new topic” “featured image”, I select the picture…when I turn back to the topic, no picture. It doesn’t remain selected.
I use the latest WordPress: 4.30.
I tried creating a plugin from the code above, but I couldn’t activate it. Can someone please help me with a step by step fix for a regular WP install?
I had already got to the stage of banging my head against the wall a few times because of this, but now it’s finally sorted out and my forums don’t throw up those nasty 404s when validating and being indexed by search engines.
