Make sure you have pasted your API Key in Wappler properly, and then make sure in your google developer portal you have the type of map api enabled that you are trying to use.
Check your browser console window for more info. Check to make sure you have your domain name enabled for that google maps api.
Just to test it, turn off all restrictions. Give it a few minutes and check again. If it works, start adding them back one at a time. Like Teodor said and the error message I posted, it’s a site restriction issue.
Ok I actually found what the error is. Ir used to be that you would just go in and set up an api key. Now google wants you to sign up for cloud services even on free account. So you have to set that up. But thank you every one.
