Work through the checklist below to identify and fix map display problems in FW Real Estate.
The map feature requires the FW Real Estate - Map View plugin to be active. Check that it is enabled in one of two places:
Without a valid API key, Google Maps loads briefly then overlays an error message and does not display the property location pin. Enter your key under Settings → General → Map View in the Google Maps API key field. Open your browser's developer console (F12) to see the exact error message returned by Google, which will indicate whether the key is missing, invalid, or has incorrect permissions.

FW Real Estate requires two separate Google API keys with different restriction types:
Using the same key for both purposes will not work. If geocoding appears to do nothing when saving a property, a mismatched restriction type is the most likely cause.
Properties with no latitude and longitude set do not appear on the Map View layout or the listing page map. Open the property in the admin edit form, scroll to the Map section, and set the coordinates using one of these methods:

If the map was working previously but has stopped, check your Google Cloud Console for quota limits and billing status. Exceeded quotas or a suspended billing account will prevent maps and geocoding from loading.
If you have selected Map Box as your map provider, verify that the token entered in the MapBox API key field is current and has not been revoked. Log in to your MapBox account at mapbox.com to check the token status and generate a new one if needed.
