Members Unable to Login

Hello,

On a member account:
When the account is first created or logged in for the first time on a new browser, I am able to access restricted content, edit profile, and my alt logged-in menu is displayed (because the member IS LOGGED IN). If I manually log out, I am no longer able to log in, I am simply redirected to the profile page but am NOT LOGGED IN and am not able to access restricted content, edit profile, or view alt logged-in menu.

I attempted to rollback to a previous version (solution by others who have posted similar issues) but the login issue remains. I need help, thank you!
