Sorry for the multiple replies, I can’t find an edit button.
@modemlooper is there somebody you could suggest would be best to speak with about this particular issue? Or maybe a specific forum area I should be posting in more specifically than just general troubleshooting?
Also, I forgot to mention – does doing this also effect the items in the drop down menu that filters the Activity Stream? I want people to be able to filter the stream by this custom post type. Is that the same issue or is that a different issue?
