    As you website is offline, I cannot see what issue could be. I have created the Azure AD option, and filled in the needed IDs but getting a critical error. How to solve?

    So this sound similar to this issue:

    Have you checked you have the Google Listings plugin? If other plugins have implemented these third party plugins poorly, a error will occur, that’s not much I can do about that as I can’t change other plugin’s code. As far as I’m aware, I have loaded these libraries correctly, and they are namespaced.

    It was indeed the plugin from google. Have deactivated it and now all works fine!
    Thanks for support!
