Why Listdom Map Is Not Loading? (Invalid Lat/Lng Coordinates)

If your map is not loading and the browser console shows an error like:

Invalid LatLng object: (37,0625, -95,677068)

…it means the coordinates stored for one or more listings are not in the correct format.

Symptoms

• Map area appears blank or grey
• No markers are displayed
• The map container collapses
• The console shows an “Invalid LatLng object” error
• Leaflet or Google Maps script fails to initialize

Why This Happens?

Listdom expects coordinates in this format:

37.0625, -95.677068

But some servers, imports, or plugins replace decimal points with commas:

37,0625, -95,677068 ❌ invalid

Leaflet, Google Maps, and Mapbox do NOT accept comma decimals, causing the map to break.

How to Fix It

1. Edit the listing and correct the coordinates

Go to Listings → Edit Listing → Address (Map Picker)

1. Delete the invalid latitude and longitude.
2. Use the map picker to generate new coordinates.
3. Save the listing.

2. Check all imported listings

If the listings came from a CSV import:

1. Open your CSV file
2. Make sure coordinates use dot notation, not commas
3. Re-import if needed

Correct:

50.123456

Incorrect:

50,123456

3. Fix server locale converting dots to commas

Some hosting environments use de_DE, pl_PL, or other locales that auto-format numbers.

Ask your hosting provider to set PHP locale to:

en_US.UTF-8

This prevents automatic comma conversion.

4. Remove the listing with invalid coordinates (temporary fix)

If you need the map working immediately:

1. Check the browser console.
2. The coordinates appearing in the error belong to one listing.
3. Edit or temporarily unpublish that listing.

Additional Notes

• This error breaks the entire map, even if only one listing has invalid coordinates.
• It affects all map sources: Google Maps, Leaflet, Mapbox, Bing.

Conclusion

If your map shows an “Invalid LatLng” error, the cause is almost always comma-based coordinates. Correcting the formatting in listings will immediately resolve the issue.
