Reply To: login/registration pages “not found”
If you go to Appearance/Menus in WP Admin, you should be able to edit the menu and delete those links. While you are there, click on Page Options on the top right of the page and make sure BuddyPress is checked.
Note: it looks like you have multiple menus so you will have to select the correct menu to edit.
Then you should see the BuddyPress menu links meta-box and you will see there’s a login link you can add to the menu. That should sort out your BuddyPress login, same with Register.
I’ve got a site buddyuser dot com, I’ve created a beginners introduction to BuddyPress, you might want to take a look at that.
It’s possible to hide menu links that you don’t want the general public to know about. There’s a few plugins that do this but one I use is https://wordpress.org/plugins/nav-menu-roles/ this adds a handy checkbox to allow you to stipulate who can see that menu item.
