Thank you for getting back. Here is a link to a screen grab showing the map as I see it on the SURFACE Windows 8.1
In the SURFACE I was viewing in Explorer.
On my PC the map works correctly on the following Browsers: Google Chrome; Explorer; Firefox; Safari.
The company who developed and continue to manage our WordPress website are aware of the potential conflicts from plugins and themes etc. When we initially discovered the issue with the maps, we did turn off all other plugins etc apart from MapPress but the issue still remained. They suggested I post the issue on your forum which I did in an attempt to find a resolution.
