Hi Robert, I backed up my site and DB then I aimed my name servers at a new host and the next morning I uploaded the site to the new host.
All my maps and markers were there but it was clear something was working quite right.
So I deactivated and deleted the plugin and reinstalled (I also ran a DB optimizer) I deactivated all plugins and then reactivated them a few at a time. All seems to be working now.
But! when I create a layer, it seems to be working and when I add the marker, all seems good. But when I go to preview the layer it shows the correct map but not the marker. (I added no code and left the text in the marker plain). I have a screen shot in an email if you want that..
The marker shows up in the text box under the map where all the markers normally show up. I also had to reset all the defaults to get it running so I'm wondering if the defaults may have something pointing to the wrong location and I haven't spotted it?
