Hi Robert,
I had already tried everything except de-activating and re-activating the plug-ins. Didn’t want to kneecap my site. But I solved the issue ??
Just wanted to share it quickly in case anyone else has this problem :
In the Overlays Tab in Settings in the Custom Overlay Settings section the last option is the following – Show errorTile-images if map could not be loaded?
I had true chosen and when I switched it to false the errorTile images stopped appearing. The weird thing was that the maps were loading fine (I could see them loading before the errorTile images appeared every time) and for whatever reason they were showing up on top.
Hope that helps.
Great Plug-in btw Robert!
Jon
