Hi, this is usually caused by an issue with a marker. You can find a list of your markers in the map editor under the Marker tab. If you remove your latest markers the issue should be resolved.

There are no markers on the map. None. In fact, I deleted my previous map and created a new one from scratch to fix the issue. It didn't help, and it has had no markers.

I am really sorry I cannot reproduce this and the fact that it works for another map seems to be pointing either in a temporary connection error or a content issue.

Some troubleshooting later: I had created a custom pin where the name contained a + sign, which the code evidently didn't like. Renaming it didn't work, but deleting it and re-creating it with a new name did.

Thank you I will add the + sign in the list of not allowed characters!
