New Graph (Graph) not working after upgrade to 7.5.1


When I try to add a Dashlet (Chart) nothing happens. If I go to console (browser dev mode) it says:

Blocked a frame with origin "" from accessing a frame with origin "".  The frame requesting access has a protocol of "https", the frame being accessed has a protocol of "http". Protocols must match.

Any suggestions?
