Cannot read error message in "Edit Data Source"

I have a brand new install of grafana-4.6.3-1.x86_64.rpm on a RHEL7 server.

Graphite is up and running no issue on the same server. “rbox” is what it’s named. It’s listening on localhost port 8080 so I choose proxy.

When I try and add graphite as a data source, a red box comes up but there is no text in the box to tell me what the issue is. I set logging to debug and this is all the logs shows me.

Are you running Graphite version >= 1.0, otherwise please select the correct version when creating the datasource.
