Alex,
I use a theme called Voyage (from themefuse.com) and they have custom posts for the holidays. Your plugin does not work on these custom posts, that means the map plugin is not below the editor. For the normal posts/pages it's below the editor, but not for these custom posts.
Further more, the custom posts have content tabs and I want to put the google map in the content tabs. I have created the maps with your shortcode builder and posted it in the tabs. However, the map is shown only partly, only a tiny frame on the upper left is shown, the rest is gray.
Any idea?
thanks marc
