New Installation Help

I have installed and activated the MapMe plugin, entered my GoogleMap key, but I see nothing on the main screen referencing the plugin.

Also, I don't see any entry in the "Menus" function to add it to any location on the main screen.

The theme I'm using is:

Jayya

what is link to your website where you're using it. Also.. try re-uploading plugin's PHP files in binary ftp mode.
