Google maps markers don't appear on the map


I’m having a problem with my google maps on the website on:

I’ve implemented all the markers properly and on the backend of the website I get a nice preview of the whole map showing all the red markers on the map, that I’ve implemented. (see screenshot 1)

But when I check on the live-side of my website, I can zoom in and out on the map, but the markers are not showing. (see screenshot 2)

Can you help me out?

Hello, it looks like WP Google Maps Pro plugin issue.

You can try to contact its support and see what they say.

Kind Regards, Roman.
