Hello,
you only need on API Key per site, so if you are going to add the key inside the GeoDirectory settings, then you can disable and delete the other plugin.
Right now your site has the following error:
util.js:226 Google Maps JavaScript API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
To get a new key, please use the option at
Geodirectory – Design – Map – Generate API Key (Button)
Try out the key before adding security to see if it works. Make sure when you copy and paste that there are no extra spaces before the key.
It can take some time for a new key to work. This is a Google issue, and may take 5 minutes at least, BUT, the key will not throw errors. So once your key is installed you can reload the page and check for errors.
Once you see “Google API Loaded” and no other Google API related errors in the console it is just a matter of time until it works, and you can start adding your security.
The idea is to know if your key is at issue, or the security settings.
