I'm running a Joomla! 3.3.0 installation and the front-end is fine, however I'm getting a Uncaught TypeError: undefined is not a function in the back end that is really annoying.
When the error occurs, the "Search Tools" button doesn't work and I can't search a keyword, and the article/module edit page doesn't display any tabs.
This is really strange behavior since the error can disappear if I refresh the page a few times.
I realise this is most probably a Mootools/jQuery conflict, but in theory everything is the way it should be regarding noConflict being enabled.
Here is the error I get:
Uncaught TypeError: undefined is not a function -> index.php?option=com_content&view=articles:206
The lines where the error is displayed:
jQuery(document).ready(function (){
jQuery('select').chosen({"disable_search_threshold":10,"allow_single_deselect":true,"placeholder_text_multiple":"Selecione alguma op\u00e7\u00e3o","placeholder_text_single":"Selecione uma op\u00e7\u00e3o","no_results_text":"Sem resultados correspondentes"});
});
I'm using Isis template whit no modifications

I already tried plugins Mootools Enabler/Disabler and jQuery Easy with no luck, all they do is to break both front and back-end if I disable mootools or mootools-more.
I figured it out.
The problem was a conflict with the plugin Javascript Async & Defer.
With it disabled the problem is gone.
