Using map_only="1" attribute not work in Joomla! plugin

[ccyeh0901]

Hi~ I just installed ggpkg plug in my Joomla! project and show the ggpkg data succesfully, As I want to show only the map (which is a floor plan custom made), ,
Here is the short code I use to show only the map
{ggpkg file="now" map_only="1"}

but not work, show blank screen and see only warning message "Google Maps JavaScript API warning: NoApiKeys" in cosole, but my floor plan is not concerned with goole map.

if I remove map_only="1", ggpkg is shown again.

Just wonder if anyone have this problem, and any suggestion is much appreciated

Hi,
Have you set your Map API key in the skin?
Please see this page: https://ggnome.com/doc/google-api/
You need the Map Element API.

Thanks, I've filled the google map API key with no any restriction set but still get the same message "Google Maps JavaScript API warning: NoApiKeys"~ Besides, I didn't use the google map but my own floor plan map....><
BTW, I wonder if I can switch to map_only mode in a pano2vr project, because I have a project may show the floor plan(map) only, no need to go into the panorama scene. Thanks very much~~
