A bug in Chrome v51.0.2704.63 causes it to error when loading OpsCenter. The symptoms are:
- OpsCenter will not load completely, and will instead hang at the "Loading OpsCenter..." message
- in the JS console, an error is logged: "Uncaught ReferenceError: normal is not defined"
The issue has already been fixed in the latest release of Chrome; simply updating Chrome should resolve the problem.
