I tried to switch to another theme and saw messed Main Manu, without Register page. When I switched back to Anchor theme, Widgets broke down so I had to set it again. Theme author told me that they intergrated a lot of plug-ins in order to provide users more options and that sometimes Jetpack can cause problems.
Anyway answer was: ” BuddyPress isn’t part of our theme neither our AIT plugins. That’s why I cannot support this issue. For compatibility with third party plugins please contact their support”.
I am sure that I associated the proper page because there is only one Register Page that I created. As I imported Demo version of the theme I had to make my own menu, but there are stil a lot of pages that I got with importing settings that are not visible now.
When I switch to othere theme – I lose Menu that I created and I see all pages that are created, but no Register page?
