I've installed your Plugin and it works well except with one of my other plugins: Google-Maps-GPX-Viewer
I contacted the developer, told him about my problem and he wrote that "another" plugin creates masses of metas which destroy the of the plugin parsed content.
Usually the plugin should show up a google map created automatically from a GPX-File on my server implemented into my article. But the boxes where the maps should show up stay grey.
You can have a look at one of these articles here: http://www.abenteuersuechtig.de/index.php/motorradfahren-in-der-schweiz/
Thanks in advance.
