My website uses the Google maps API (3.0) in a very heavy way. I had to register my application with Google APIs Console.
In the \"referers\" section I put *.w
*.w
There is no single pattern that matches both cases, you must use 2 referers
*.websitename.com/* websitename.com/*
EDIT : Keep in mind that sometimes it needs 5 minutes for changes to take effect.
