Google will no longer recognize addresses

when i made my app live it no longer recognizes any entered addresses as addresses I have a API key and have put it in but nothing seems to work.

I am assuming you mean the Google Places API…

From what you have described the API key must probably be associated with your “Development URL”.
You will need to create a new API key and associate that with your “Live URL”

Or you could also associate the key to both the URLs, rather than creating 2 separate keys
