Unauthorized to view login page after upgrade

Hello, i have a joomla3 website with CB a some plugins. It's working fine right now.
I've copied the webiste on another test server, removed alle 3d party extensiosn except CB ones and i've updated everythig. Update to J5 went smooth.
I only have a problem: i have a login/register page that is set on "guest" (1st screenshot).
Joomla's user registration is set on "no" and in CB config i have "yes, independent..."
When i click, as a guest, on the menu item i get a white page with only "You are not authorized to view this page!".
On the 2nd attachment you will find all the CB plugins i have installed.
Since i've changed a bit from the joomla3 website whant am i missing here?
Thank you!

Within CB > Configuration > General be sure "Login Method" is set to a login method and save configuration. Login page can only show that when "Login Method" is set to "None".

Thanks, it was indeed that option. It was "username", i had to switch to another one than save, then return to "username" again and now it works.
Thanks!
