Register button not working

Hi

Since yesterday the built in Register button in the navmenu has stopped working well it works but takes me to a page which isnt registration page.
The sign in option works.
I havent changed anything for this error to happen. I have woforo which had for several days and the registration was working then.

The only thing i have changed recently is the role permissions in wpbakery disabled all options for gamer role.
