Database login stopped to work (solved)

Hello. My database login just stopped to work.

I get this error on the console:

Failed to load https://audiogrooves.auth0.com/usernamepassword/login: Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘https://audiogrooves.net’ is therefore not allowed access.

Any help please?

Fixed. It’s the idiot cache from Chrome.
