…wp pages redirect…

hello, I noticed that in some cases, users are not redirected to the correspondant wp page, created to avoid user to access the backend.

I’m working on a brand new site using the sabai directory plugin that, when user is not signed in, asks for registration/login. if I click on login link, I’m transferred to the original wp page under wp-admin instead of the registration page with wpum code.

if needed, I can give you URL so you can see by yourself.
thanks for now
