I just recently upgraded to Sitefinity v. 8.1 and when I am attempting to create a new Template using the Bootstrap templates and I the following error message.
I'm getting a similar issue. Upgraded from 8.0 to 8.1, getting the following errors:
"The file '/afwh/MVC/Views/Navigation/NavigationView.Horizontal.cshtml' does not exist."
"Cannot find template "~/Frontend-Assembly/Telerik.Sitefinity.Frontend/GridSystem/Templates/grid-4+4+4.html"
I've remove and re-added references.
So far I'd rate this upgrade experience a 1/10.
