title: Wordpress theme Flatsome 3.11: UX Builder not loading
body: <p>I've just installed Flatsome theme version 3.11.0, wordpress 5.4, php 7.4, mysql 8.0 on my SSL protected site. </p>
  
  <p>I disable all plugins, not even one.
  First, I can edit home page easily. But when I edit other page, like contact, about... it was not loaded.
  I checked console, has a error in image 1.</p>
  
  <pre><code>Uncaught TypeError: Cannot read property 'isRoot' of undefined
      at t.value (editor.js?ver=3.11.0:2)
  </code></pre>
  
  <p>But I refreshed page while console opened, no error display in image 2. 
  That error only show when console closed.</p>
  
  <p>Please help me, thank you so much.</p>
