I have an issue where locally (IIS EXPRESS), the SimpleRedirects module works correctly. But on the production site, it only will list redirects added in the past, and I can not do anything else (search, save, delete, etc).

I did a comparison and the files are the same between the instances.

I did notice that in the debug view, the "Sources" tab shows App_Plugins and umbraco being loaded, but not on the production server.
