Google Maps MissingKeyMapError

Hello,
I’m getting MissingKeyMapError when loading a Google Maps layer (although I’ve set a valid API Key in Settings > Google Maps API). The map displays for one second and then shows an error message “Ops, sth went wrong”. Same result if I don’t set any key.

Until yersterday, I was using keyless access for Google Maps and it worked fine, but according to this official announcement: https://googlegeodevelopers.blogspot.com.ar/2016/06/building-for-scale-updates-to-google.html it’s no longer supported. So, as far as I understand, there is no other alternative than setting an API key.

Here is the map I’m using: http://www.aiepba.org/servicios/siloa/
Now I’ve changed the default map to Mapquest as a workaround, but the problem can still be reproduced selecting the Google Maps layer (any of them).

I’m using plugin version 3.10.4. I know it’s not the latest version, but I didn’t find any changes related to this in version 3.10.5.

Is there something I’m doing wrong?

Thanks.

Natalia.
