I'm debugging my jQuery DataTable using Firebug. So, in the Firebub panel I see:
<div id="newspaper-b_length" class="dataTables_length">
<label>
Show
<select name="newspaper-b_length" size="1" aria-controls="newspaper-b">
entries
</label>
</div>
but I don't have this piece of code in my php files. How actually I can find these lines of code in my php files?
