Hi, the MapPress javascripts aren’t on the page (you should see mappress.min.js). Something is probably removing them.
Are you using some kind of minifying plugin? Try deactivating all plugins and switching to 2012, then reactivate to find the problem. Also, please check the FAQ:
I tried the default theme and the map loaded. My footer.php does contain <?php wp_footer(); ?>, its weird because half the stuff is being called for the map :\
Just checked, and some js from other plugins is not being loaded in the footer either. Changing themes fixes the issue. I tried the validator to check on the html and its ok.
I guess I am missing something else from the template system (I’ve checked the code in header/footer/index.php and everything is there :\)
