I added the second key as described, though the page you directed me to doesn’t look like the page I see.
No change, the site still won’t accept street addresses, only long. & lat. addresses.
You say look at the chrome console. I’m not sure where that is or how to find it. Google is no help with that either.
This is supposed to be a no-code plugin and should not be so hard to set up. I’ve set up other geo-type programs such as the Time.ly calendar and there is no difficulty with addresses.
