Hi Etienne,
Thanks for reaching out to us 🙂 I’m sorry to hear about the issues you are having with our product…
First of all I’ll need you to open different tickets for your different issues, that way they can be addressed simultaneously by different team members. It also makes it easier for other users to find and benefit from the answers. I will be addressing the map issue in this thread.
I’ve looked into your site, specifically this event: http://www.maddyness.com/agenda/ces-2016/ and I see there are many JavaScript errors in the browser console. Can you fix them? They can be the cause for the map not showing. If the problem persists after fixing this errors, please share an event URL where the map should be showing up.
Please let me know about this,
Best,
Nico
