If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
You shouldn't be using an iFrame for something like Google Maps that you can embed straight into your site. You should use the Google Maps widget in the Yola Sidebar, or get the HTML of the widget and put it inside a styled div, as Lee suggested.
