Google Maps add-ons are refusing to Activate

Hi,

I am trying to activate the following add ons:

Google Places support
Map location shortcode
Responsive maps

When I click on the Activate link for any of these add ons, the page loads (URL: http://janusrainmaker.wpengine.com/wp-admin/options-general.php?page=agm_google_maps&settings-updated=true#add-ons), but nothing activates!

I have tried it several times. What could the problem be? I have activated Support Access for you.

Thanks,

David
