It appears that the plugin is incorrectly modifying the URL which is used to request Maps satellite imagery. Here you can make a comparison between the two formats.
Website (failed request) khms0.googleapis.com/kh
?[object Map Iterator]=[object Map Iterator] Working sample request khms0.googleapis.com/kh?v=908&hl=en-GB&x=9656&y=12316&z=15
I suggest working closely with the developer of the plugin to see you can locate how and where this behaviour is happening, I suspect that this is due to the ability of the plugin to switch between other third party map types and possibly services.
