Errors in the console

I am so newbie i don’t know if i have to worry

No, you don’t have to worry, this is not your code that showed this warning. Sorry it’s ugly.

As a workaround, if you:

  1. use “Show In a New Window” instead of “Show Next to the Code”
  2. delete the Glitch button from the bottom of index.html if you are including it - these four lines:
    <!-- include the Glitch button to show what the webpage is about and
          to make it easier for folks to view source and remix -->
    <div class="glitchButton" style="position:fixed;top:20px;right:20px;"></div>
    <script src="https://button.glitch.me/button.js"></script>

then the warnings will not show in the chrome dev console, and you can debug in peace.

Hope this helps,

Thank you for your reply.
The warnings are gone without any actions ?
