Sorry you ran into issues here. Blank maps can happen for a variety of reasons. Do any of these sound like they might be happening in your site?
1) You recently imported a large number of listings. If you did this, the Google Maps API has a daily limit of calls made to it and can be exceeded during the process. Waiting 24 hours usually takes care of the problem as you’ll get a new allocation of calls the next day. Once BD’s Maps module can get the geolocation data, we cache it. This is probably the most common cause.
2) You’re using a theme or other plugin that is using the Google Maps API as well. The limit is imposed for all calls made from the server, so if your other software has used them up for the day, the map is blank until it can get the data. This is less common, but can happen.
3) You’re on a shared hosting plan and someone else is using the Google Maps API on your server besides you. The calls are allocated per IP address, so a shared host means shared calls. This is the least common, but we see it occasionally.
4) You haven’t mapped the listing fields on the Maps tab OR your listing doesn’t have any address/location data. Without anything to locate with, the Map won’t actually appear.
In first two cases, the first thing to do is wait 24 hours and see if the maps appear on their own. If not, then the next thing to check is to see if the Maps are having some kind of conflict, but it’s best to know if they restore on their own first.
But if this is a new setup–you may just be missing the field association for maps to use for geolocation. Try those and report back.
