After login all pages directed to protected page (latest membership plugin)

I have granted access, please help to solve this critical problem.
After login, all pages directed to protected page (latest membership plugin).
I need to use another browser to do the successful login for the first time. After I clicked logout and try to log in again, it will redirect any page I access to protected page. Any idea what happened?

Last time I try to reinstall my wordpress, and problem solved.
But this time it doesn't work with this solution.
