I have managed to fix the problem. I created a page called My Account and placed it in the top menu. I was supposed to put the BuddyPress profile page there instead.
Now im just baffled as to how it was working the other day, considering it’s a different page. Oh well haha. It’s working now anyway.
How does a member view their profile? And change settings etc. Would I have to click on the members page and go from there? Or is there supposed to be a profile BP user menu like the one above?
