Threads created by users that are not the creators of the page, will not appear in their profiles. Instead, the feed appears in the profile of the creator of the page. That's how phpfox works.
We want that every thread a user post, will appear on their profiles, even if this users isn't the creator of the page. This also includes a reply on a thread that another user has posted. The thread may not be appear on the profile of the creator of the page. Just like a social network should work.
