Opencart 2.3 Notice: Undefined property: Proxy:: function_name
<p>I am working on Opencart 2.3, I have installed a new extension into the system and since then I am getting an error in the product description page in the front end:</p>

<blockquote>
  <p>Undefined property: Proxy:: function_name**</p>
</blockquote>

<p>The uploaded extension is in the admin section, the product description page was working fine before installing the new extension. </p>

<p>Note: The extension has vqmod file and modification folder has the files related to the extension.</p>
