Similarly after activating WP Google Maps you will get the Map menu in your Admin Panel. From here you will be able to add the map in your theme .
Also when we locally installed the plugin we do not get any issue i.e the plugin was easily installed . So please once try to install the plugin by following the steps mentioned above . If you still cannot install then kindly let us know .
Hope this helps .
Best Regards!!
