Google Map Cluster Pin not working

Not sure what happened but the cluster pins suddenly quit showing up on my google map on https://www.cyclingchicks.xyz/

I made a change suggested by https://premium.wpmudev.org/forums/topic/turn-off-pop-up-when-you-hover-over-a-pin?replies=6#post-1079871 but then reversed it as it caused an error on my site. I haven't tried the last change suggested yet since I found this other issue.
