I've just upgraded from TFS 2013.4 to TFS 2015, and all was looking good. Now the page content is not loading in web access due to the following errors on multiple lines: Uncaught ReferenceError: require is not defined.
For example, when trying to load the project page (http://[server]/tfs/DefaultCollection/[project]), I get the above error on lines 38, 44, 117, and 173.
Our configuration is all pretty straightforward, with the only addition being a hostname binding on the IIS site that uses port 80. We still use the default port 8080 for TFS configuration.
Any idea what may have happened to cause this error to start popping up? Thanks!
