After a bit of fumbling I finally enabled the oauth plugin. My organization (who I'm setting up the wiki for) uses GSuite and we wanted to make it the only way to log in. I got it working, and now new users are able to quickly sign in uses oauth and their work google account. Unfortunately, my work email account was tied to the admin account from before I used the oauth plugin.
I made the mistake of not enabling google login for my own account before I swapped over to oauth. Now, when I try to login using oauth I get to the google account selection page, select my account, and am redirected back to our homepage with the following error message at the top of the page:
The account associated with your email address has not enabled logging in with Google. Please login by other means and enable it in your profile.
Unfortunately the only login option now is with Google. The correct email is associated with the admin account--I just need to be able to log in once to tick that box! Any help is greatly appreciated! Also, I apologize if this is the wrong place to post. I'll happily take any redirection suggestions.
