Safari won't show Google Maps
Just recently I can't get Safari to display Google Maps - I'm using version 9.0.3. I do a Google search for Google Maps and it shows a URL of https://maps.google.co.uk but if I click on the link it translates to https://www.google.co.uk/maps and all I get is either a blank page or one that just shows the words "Google Maps" in the top left corner, with no notification that anything is wrong.
There was a suggestion in another thread that this was a problem with the DNS name servers but i already use the OpenDNS ones, and I have no problem at all with Firefox which shows the maps properly. If I copy the URL that Firefox is using into Safari I get the same result as before. What can be causing this problem?
