title: The provided Google API key is invalid due to Error Code: InvalidKeyOrUnauthorizedURLMapError
body: <p>I followed the Google tutorial on how to generate an API key for browser however I am unable to load the map due to error with invalid key.</p>
  
  <p>None of the solutions posted to related issue worked in my case.</p>
  
  <p>This is my code:</p>
  
  <pre><code>    &lt;head&gt; 
    &lt;meta http-equiv="content-type" content="text/html; charset=UTF-8" /&gt; 
    &lt;title&gt;myTitle&lt;/title&gt; 
  
  &lt;script src="https://maps.googleapis.com/maps/api/js?key=MYKEY"
    type="text/javascript"&gt;&lt;/script&gt;
  
  &lt;/head&gt; 
  </code></pre>
  
  <p>Web console log:</p>
  
  <pre><code>    "ApiNotActivatedMapError: https://developers.google.com/maps/documentation/javascript/tutorial#api_key" main.js line 61 &gt; eval:50:381
