I am still receiving this error even after applying the solution listed in this post.
I seem to be getting a 401 unauthorized message when getting to the page template selection page. ( /CMSModules/Content/CMSDesk/MVC/TemplateSelection.aspx )
This page tries to get filtered page templates from the MVC site but throws that unauthorized message. If I visit the filtered page templates URL in a new tab it loads fine.
Has anyone experienced this as well?
Resolved my issue. This issue was not directly related to the service pack but with custom configuration within my solution.
