Wordpress id console error not defined

I get this error message from the wordpress theme in the console. I do not know how to fix it. How could it even be called empty?

errror:

Uncaught ReferenceError: qode_startit_style_dynamic is not defined

Error line:

   <script type="text/javascript" id="qode_startit-custom-js">(function($) {qode_startit_style_dynamic('jquery');})(jQuery)</script></body>

Thank you very much !!
