I uninstalled QGIS and removed all files on the computer with QGIS in them. I then reinstalled version 2.8. I still get the same problem that google streetmaps does not display. When I try one of the other options in the openlayers plugin I get this.
These little question marks suggest a problem with the graphics of this layer. How do I get Openlayers working?
EDIT: UPDATE: It works on a home pc not at work which has a proxy. We have tried fiddling with the proxy but to no avail.
