Ciao
I discovered a stupid bug, when you are going to the plug in configuration, and click into help button bottom there is a sentence that say: Bugs, problems, thanks and anything else here!
When you click there, the link that you are redirected is “http://www.darwinner.it/forums/forum/wp-gpx-maps/” which is wrong, there is nothing there.
I guess you have to upgrade the link to go to the real support link, this page.
Gracie mile.
