I fixed the second & third issue but I am still stuck at the first one.

Looking at the markup I found <select name="forum_id" id="forum-id""> is being generated by bbPress codebut the same works in default theme flawlessly so this isn’t the cause. Can I have the complete lookup order for file required to generate the “Add new” page.
