Remove ids from article urls in Joomla
It quite simple, no big hacks. In fact, Joomla already had it build in, it is just not shown in the admin menu (don't ask us why.
simple change the file: administrator\components\com_content\config.xml.
and add somewhere between the other items:
label="Sef Advanced Mode"
description="Remove ItemID from Content URL?">
Now go back to your article options, and you have a new option :) SEF Advanced Modus, just put it on and your done :)
