Code Review not showing preview

[Jacob Polacek]

Usually upon clicking a file that was added through "Add Content" within a code review, you are able to see the source code and there is a line saying "Add a file comment. Click on source lines to add an inline comment." The issue I'm running into is that I only see "Add a file comment." followed by a box that says "New Version" and contains a link that says "Download revision <Change List Number>" instead of the source code.

So far, I have tried removing all of the files, adding different revisions, and downloading the revision. 

The only thing I can think of is that the files are not supported (is that possible?) because the file icons are different in the ones I can view compared to the ones that I cannot view. The files are .cs, .csproj, .pdf, .nunit, and .sln if that makes anything clearer.

Does anyone know why this is happening/how to fix it so the files are visible?

We are having the same issue, Crucible is hooked up to Github, can view all the info but the code view won't display.
