Tags input autocomplete not working

Hello, I have a bug with the Tags Input Feild. There is the error in the console :

Uncaught TypeError: jQuery(...).tagsinput is not a function

I think it’s related with

jQuery(document).ready(function(){

inside tags-for-anspress/theme/js/tags_js.js.

When I remove this document ready function, I don’t see the bug inside the console anymore.

But, the tags input autocomplete still don’t work ?

Thank you for helping me! 🙂
