“For development purposes only” error on Google basemaps

By default Maps Marker Pro uses OpenStreetMap for maps which can be used without any mandatory API key registration. If you are using Google Maps though, you can experience the following issue, if the Google API key setup was incomplete/incorrect:

If you see the error “For development purposes only” on your map using Google basemaps, please open your browser console (e.g. by pressing the key F12 in Firefox or Chrome) and switch to the “Console” tab e to see more details about the error:

In the example above, the error is NoApiKeys, which means the mandatory Google Maps Javascript API key is missing.

Anyway most errors are related to your Google Maps Javascript API key, which is needed in order to display Google Maps properly.

So to fix this, please proceed as follows:

  1. make sure you registered a Google Maps Javascript API key, see tutorial for details. Please also make sure that you have saved your credit card details in the Google API console, which is needed since the Google ToS changes from summer 2018.
  2. if your error is RefererNotAllowedMapError please re-check step 6 from the tutorial and make sure you set the your accepted referrer for the domain where the map is embedded is configured correctly, like *.yourdomain.com/*

For all other errors please have a look at the error reference at https://developers.google.com/maps/documentation/javascript/error-messages#deverrorcodes where you will also find a possible solution.

If this still does not help, please open a support ticket and we will be glad to help.

    You can also get this error if you don’t have billing account at Google. From June 2019 goole changes the rules, if you don’t have billing account then developer only watermark will be visible to the user.
