No problem, the issue lyes that the user should Create a Login menu item if they want to allow users to login. But previously they didn't mind, however, they force the homepage menu item on the redirect url since they do not have one to go off when redirecting to login. But then the login page is restricted like the original menu item, so it's creates a loop.
I had solved it, but it didn't work on multilingual and it's getting time to solve it or someone else to solve it.
Many thanks
