I had a look at your site, and the map appears to be displayed properly:

Have you managed to solve the issue by yourself?
Hey, thanks for checking out.
Yes, I deactivated all plugins and then reactivated them one by one… and I discovered a conflict with the plugin “Boxers and Swipers”.
I set the plugin (Boxers & Swipers) to use Photoswipe in all screen widths. Don’t know if this is useful information, though.
Thanks again!
