The problem is when the plugin tries to load the bar using the page embedded script and the object ‘wpfront_notification_bar’ is still not created (because it is created in a JS file):
HTML FILE:
<script>
if(typeof wpfront_notification_bar == "function") ...
I’d add a jQuery ready event to run the embedded script to wait until the ‘wpfront_notification_bar’ object is created. Something like this:
jQuery(document).ready(function() {if(typeof wpfront_notification_bar == "function")
But it should be made in the plugin PHP classes.
