title: JQuery stops working without any error message
body: <p>I noticed on my website that jQuery stops working but I get no error on the console.
  I have been trying to test it with very basic code but still the jquery library is loading well, the javascript code works but not the jQuery.
  I tested it with Chrome and Internet Explorer on two different computers.
  Could someone point me to a direction to look for this problem please ?</p>

  &lt;h1&gt;JQuery&lt;/h1&gt;
  &lt;p&gt;hide me please&lt;/p&gt;
  
  &lt;p id="demo"&gt;demo&lt;/p&gt;
  
  &lt;script&gt;
  document.getElementById("demo").innerHTML = "My First JavaScript";
  &lt;/script&gt;
