Hello,
I got the same problem. Everything was ok couple of months, but 2-3 days ago I lost a login of admin. Now the whole site is worthless. I can login to the WCFM dashboard, but not in WP.
Hard to choose anyway. I decided to keep Tutor LMS and deactivated WCFM.
The same problem still exist. Anybody found any fixing for that? Or from Tutor LMS side? I tried to inspect everything, but not any idea. It shows /settings, but in reality it is at home (/store manager). As soon as deactivate plugin, everything works.
