I noticed a comment saying not to use BuddyPress, which afterwards i uninstalled from my forum.
In the comments section it linked me to this post on here

I have followed the post which mentioned to go to the Dashboard > Appearance > Menus. Find wpForo navigation in the drop-down, select it and enable it for the wpForo Location: Which i have done.

What i'm asking is why are my pages not working when i have everything setup as it should? this is the only thing holding me back from publishing my website to my members.
Thanks for reading.
