Map not showing despite key

Replies: 0

Hello,
I love using this plugin. However, in one of the sites I am currently using it… it doesn’t work anymore. I do have a valid API key, but the map does not show up.
It does not show up in the backend either (the preview page).

If I add a new map, it does not save it. As soon as I go somewhere else and then come back, the map is gone. Is this normal behavior?
