I have done as you said and everything seemed to be working fine.
Then I edited the Contact Us page which has a couple of Google maps. The page loads correctly to start with and the then the maps go to full screen. Have checked all the layout settings and they appear fine. Any ideas?
Well I redid the page and it works ok. The one before I used Columns with a map on one side and the address on the other and as I said looked fine in preview but when I published it the page appeared fine for a few seconds and then the maps went full screen. Re did the page with the map above the text and it works.
