Disable Plugin in Template: 
You can disable plugin filters in your template whenever you want. Maybe you need a query with a different number of custom posts per page for a specific post type. 
Using this code before your query, the filter plugin will be disabled for a specific post type:
<pre><code><?php $GLOBALS['ado_cspp_disable']="YOUR_TYPE"; ?>
</code></pre>
With this code, you can use your personalized query for your loop.
