 * Hello Support, I have WP-Maps free version 4.4.3 installed on my site. It is 
   a great plugin and has been working very well. I do not have any signs of errors
   on the front end.
 * I have been troubleshooting a podcast plugin I have installed and I keep seeing
   a persistent error in Developer Tools on Chrome “**_Uncaught ReferenceError: 
   google is not defined_**” It references your file “_/wp-content/plugins/wp-google-
   map-plugin/assets/js/vendor/infobox/infobox.js_“. and refers to line 128.
 * How do I fix this error?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Freference-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello,
   That error comes when you have not inserted the Google Maps API key in
   the back-end of the plugin. API key is required for google maps api to work and
   its the only mandatory step. I hope you have followed the instructions and setup
   an API key for your website. If you need assistance, check out this [https://www.wpmapspro.com/docs/how-to-create-an-api-key/](https://www.wpmapspro.com/docs/how-to-create-an-api-key/)
   Thank You

 * Thanks for the update. I did have a unique key installed and have had it for 
   quite a while as I have been using this plugin for a few years. The error is 
   no longer present and seems to have been transient or caused by something else.
   I am closing this ticket now and if it appears again, I will create a new one
   with more details.
