title: Your wordpress server appears to be overloaded. [SOLVED]
body: <p>I'm getting the error below when trying to call <code>gatsby develop</code>.</p>
  <pre><code> ERROR #gatsby-source-wordpress-experimental_111007 
  
   gatsby-source-wordpress  Your wordpress server at http://localwp/graphql appears to be overloaded
  
  Try reducing the requestConcurrency for content updates or the previewRequestConcurrency for previews:
  
  {
    resolve: 'gatsby-source-wordpress-experimental',
    options: {
      schema: {
        requestConcurrency: 5, // currently set to 5
        previewRequestConcurrency: 2, // currently set to 2
      }
    },
  }
  
  The GATSBY_CONCURRENT_REQUEST environment variable is no longer used to control concurrency.
  If you were previously using that, you'll need to use the settings above instead.
  </code></pre>
  <p>I tried to set requestConcurrency: 5 and previewRequestConcurrency: 2 as suggested but it was not enough.</p>
  <p>Things I did before getting error appeared that may be related:</p>
  <ul>
  <li>I updated the <code>WPGraphQL</code> plugin (v1.1.1) today (I tried to downgrade to v1.1.0 but the problem persists)</li>
  <li>I set <code>useGatsbyImage</code> (within the 'gatsby-source-wordpress-experimental' options in gatsby-config.js) to false to do some tests.</li>
  </ul>
  <p>Plugins used on Wordpress are: <code>WP Gatsby (v0.9.1)</code>,  <code>WP GraphQL (v1.1.0)</code>, <code>WP GraphQL Gutenberg (v0.3.5)</code>.</p>
  <p>I'm running a local wordpress server (via Local) and it seems to be working normally.</p>
  <p>[SOLVED] : I disabled WP GraphQL Gutenberg (v0.3.5) and it started to work again. Looks like this plugin might be overloading the wordpress server.</p>
