An error has occurred during web site deployment.

I've enabled nuget restore, and I have another MVC4 App that deploys fine.

Answer 1

To help identify the issue, I suggest starting with a clean clone of your repo on your local machine. Then run NuGet restore, and check that all the relative references in your .csproj can be resolved. It looks like it's trying to fall back to the GAC, which usually happens when relative paths are messed up.
