I am having the same issue. Everything works except “In-page Analytics” and it gives me the same error.
Problem loading In-Page Analytics
We’ve identified problems in your setup. These may cause problems loading In-Page Analytics.
Your site doesn’t load ga.js from Google. If you host the Google tracking code on your own servers, it isn’t updated automatically and can miss important changes.
We didn’t find a tracking snippet on your site. In-Page Analytics cannot load. Please make sure you have tracking installed correctly. If your snippet is included in a separate JavaScript file, you’ll have to manually check it is being loaded correc
