How to find your Google Maps API key
If you find that Google Maps on the website is not loading correctly, this article may be of great use to you. This is because Google made some changes that now require a payment account for those cases where you use more than the allotted map views per month. You do not have to pay for maps if your traffic is lower than the threshold they set, which allows for a decent amount of views. That being said, we need to make sure that you are configured correctly.
