The error that shows in the browser console is related to the referrer.
Make sure to set it to http://domain.com/* and wait a few minutes.
Also, if you manually enabled the API’s then you need more then just the Javascript API. The list of required APIs is here.
Hi Tijmen
Many thanks for your response.
I have created a new Project and API keys just to be double sure all was correct, set the domain to http://domain.com/* (yes, it was the star missing at the end that cause me the trouble) and all is working perfect now.
Thank you once again for the help 🙂
