I recently ran into a plugin conflict between PageBuilder and your plugin. It seems to cause PageBuilder's UI buttons to misalign for some reason, and it also seems to cause problems with using PageBuilder's Embed Image widget item. What happens is that this maps plugin makes the pop up dialog box within the editor pop up underneath rather than above the other dialog box, and therefore stops me from using the widget.
So I have been deactivating this maps plugin while I edit other things, which works fine. However, I recently ran into a problem wherein my entire list of stores is empty. When I go to the Manage Stores section of the plugin, all of my work is missing and cannot be edited. The page still lists that there are 21 items in the list, and yet the list is empty, and when I browse to the page that I used the wpsl embed on, the dealers load up correctly. I spent a lot of time adding these dealers to the plugin database, is there some way to correct this?
