Fix Google Maps on website

I need someone to Fix Google Maps on my clients website

Using WP Google Maps plugin.

I have an API key but it won't load.

I need the developer to also tell me exactly what they are doing to fix it so I learn something.

I can only give Google login once I have chosen the freelancer, not before.

Quick and easy job for an experience developer.

Please no timewasters.

Needs to be done in 24 hours
