404 errors on files

I have Gitlab Omnibus installed and it’s working fine for source control. But when I browse to files on the web interface, I get 404 errors on some of the files. I know that the files are in the repo because I can clone the repo and check them and compares work within my IDE.

I’m using Visual Studio and writing C# code. It apears that the .CS files 404, but .XML files (and some others) do not.

Any ideas on what I can do to fix this?
