I downloaded the Parcel Value Analysis solution which comes with an "Equity Analysis" web map. When I open it, I see that the Foreclosures and Appeals layers have an error message under them saying "An error occurred loading this layer." If I try to save the map (after making no changes), I get an error message saying the following:
Failed to save map. Relative url '{{GUID.layer0.url}}' is not supported
Do you know what's causing these errors and how to fix them? Thank you
