Cannot Login using Auth0

I am stuck. The last time I was able to login as a regular user was 2 weeks ago. My use case here is a WordPress site (single install) where users can buy access to Moodle courses, that Auth0 handles the user accounts. At this time any old or new user created in Auth0 can still login to Moodle no issue. Auth0 old and new users cannot login to my WordPress site.

Here’s what’s going on…

Situation #1
(1) Go to my site (2) Click to sign up a new user through Auth0 (3) New user created in Auth0 not WordPress. (4) After sign up form completed, the site takes me back to the main page.

Situation #2
(1) Go to my site (2) Login into a “dummy” Auth0 account I’ve created. (3) After submitting in Lock, I am taken back to the homepage, but not logged in to the WordPress site

My Application is set for a Username-Password-Authentication, so no custom databases here. All settings have not changed in about 2 months.

I’ve tried these things:
– Downgrade the plugin
– Copy over fresh Domain, Client ID, Client Secret, API Tokens.
– Copy over API Identifier and made sure correct scopes are toggled.

One thing that is peculiar is that the web address for the api v2 comes back with this error:
{"statusCode":404,"error":"Not Found","message":"Not Found"}

My site is: https://id.cogdoe.org.

Any ideas?
