I have installed SEOChecker 2.0.1 on our Umbraco 7.10.4 site. After fixing a few Autofac-related issues (which are not documented AFAIK) we still have a issue when visiting any of the settings nodes.

(For example: /umbraco#/seochecker/seochecker/generalsettings/manage).

The backend throws a generic error in any of the Initialize functions of the SEOChecker Api's.

Example URL: /umbraco/backoffice/seochecker/generalsettingsapi/initialize

Screenshot: https://www.screencast.com/t/J6YQg4Nm

The error persists after completely disabling Autofac DI.

We upgraded tot 2.1.0 but that made no difference.

Can you help us out?
