I am trying to upgrade a sitefinity instance from Sitefinity 8.0.5701 to sitefinity 11.1.6800. took a while to upgrade using nuget and had some issues after the upgrade. I had to remove some files like socialshare files and imagegallery files from the resource package before finally managing to build the solution. It builds fine and works fine on the development machine.
When I move it to our production server, it gives me an error on initialization.
Could not load file or assembly 'Telerik.Microsoft.Practices.EnterpriseLibrary.Validation' or one of its dependencies. The user name or password is incorrect. (Exception from HRESULT: 0x8007052E)
