Multiple maps in same view

In the demo-section you are displaying multiple maps in the same page. When i try to call more than one map in an article the site wont display at all. I am trying to call the plugin using {zhgooglemap:MMM;;;;;}, and it works perfectly when just adding one map, but if i try to add a second one the page goes blank. When debugging i get the following error:

Fatal Error: Cannot redeclare get_UpdateContentString() in xxx/components/com_zhgooglemap/view/zhgooglemap/tmpl/display_map_data.php on line 567

Any ideas what causes this or other ways to display several maps on the same page?

Hi

I know about that problem. You enable placemark insert (update...) from frontend. Just disable ability to create user's placemarks on this map.

Ok thanks. Can confirm that it works when disabeling frontend insert of placemarks.
