Hi Marcus,
As the error states, you have 2007 web service endpoint references (introduced in CRM 4.0 and compatible till CRM 2011) which are not supported in CRM 2013.
- Since it says Web Resource, and the actual file names are given, you can open up your CRM 2011 Organization, navigate to Settings > Customizations > Customize the System.
- In the window that opens up, click on "Web Resources" in the left navigation and you'll be presented with multiple files.
- Look for the files with the names as stated in your error, for example : "mp_/js/license/form.js".
- Double click on them, and click on "Text Editor" to see the code. Fix it to reference the new web service endpoints (2011).
Also, you can use
this tool to validate your existing code.
