URLs are broken using the plugin

Hello,

I don’t understand. What is 27defer ?

I don’t know, your script changed the ressources like that:

https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js%27%20defer=%27defer
https://ajax.googleapis.com/ajax/libs/jqueryui/1.11.2/jquery-ui.min.js%27%20defer=%27defer

Same for local ressources:

It seem that another plugin (or a php script) add (in a wrong way) an attribute defer=’defer’ to your javascript.
You should desactivate it ??

Without your plugin, all the links are correct? So the change occur by activating your plugin and is away by deactivation?

It’s because your scripts uri are https://www.heutger.net/wp-includes/js/jquery/jquery-migrate.min.js' defer='defer ( instead of https://www.heutger.net/wp-includes/js/jquery/jquery-migrate.min.js) . I think another script change your javascript URL before wp deferred javascript.
Did you use a specific plugin for cache or javascript optimisation ?

I’m using W3Total Cache
