I have an issue with a plugin (WordPress Pro Event Calendar by DPereyra) using this theme.
On single event pages the address is marked and displayed correctly, but the map itself is grey.The maps of same events are displayed correctly on widgets.
I asked for support (DPereya) and it seems that there is a conflict with the theme style.css file (https://sport-bonn.de/wp-content/themes/ionMag/style.css?ver=2.0.1) So when the map loads, all the map images are hidden but if you resize the browser you will see it again. They tried debugging the css file but it’s quite big so they proposed to ask the theme provider for a solution….
Do you know similar problems like this? Maybe you have an idea how to fix this?
Google maps are working properly when embedded in post for example. Here it seems to be a problem of opacity on the map. Please enter this code in Theme panel->Custom CSS and it should fix the issue
