Thanks @Robkk Turns out it was a plugin issue and I fixed it. I am very sorry for the late reply.
@Robkk Thanks I will contact WPMU DEV support? I didn’t see that option custom post types. Sorry for the late reply as well as I forgot to get email updates on this thread
seems like I can’t add screenshots you can see what I mean by going to http://www.gnosticthought.org/forums no site name in the browser tab all my forums so far are hidden so you won’t be able to see the sitename is there on specific forum. It’s just no working on the forums index.
