I get the title error message in my console with the map appearing in greyish, preventing me from furthering my work on this PSET.

As this API key was given while downloading the files (more precisely index.htlm), I though that other my have encountered the same issue, but I cannot find any answer online.

I thank you (whoever you will be) in advance for your help.

I used this from staff solution and it WORKED !

<!-- https://developers.google.com/maps/documentation/javascript/ -->
<script src="https://maps.googleapis.com/maps/api/js?key=AIzaSyALLIbAxCoIMyHh47Pue4moE1LyA7wvP30&v=3.exp"></script>

Substitute above HTML code in your index.html .

  • Is it ok if we use the staff's api key? Sep 19, 2018 at 20:21
  • If you are using for testing the Mashup code then it's perfectly ok :) Sep 21, 2018 at 3:06

welcome to the forum. I get the same console message, and a greyed out map with "for development purposes only". Since you are developing, this really shouldn't prevent you from making progress on the pset. Everything should still work, it just makes the map itself a little harder to read. In my case, the input box, the markers, the articles are all quite legible and useable.
