My site is www.middleeastbjj.com,

This issue i’m having is with the maps. Originally i used a different directory plugin and had issues and found out as it was to do with security certificates so i sorted that and then had it working. However i didn’t like the plugin so switched it up to listify theme which came with the wp jobs manager plugin to manage the directory. However i’m now having problems with the map. I’ve tried both google maps and map box and neither work. Specifically when i search or do anything location related off the front page search or off the listings page i get this error ‘
Oops! Something went wrong.
This page didn’t load Google Maps correctly. See the JavaScript console for technical details.’

i’ve obviously inserted my api key etc, please help?
