Sometimes you really want your latest posted article to show up on top of the stack on your fancy dandy groovy Joomla site. Quite a normal desire, I might add...

An always excellent start is to go in your Joomla backend > Menu manager > pick up your menu > edit menu item > parameters [advanced] > Category order / Primary order > Most recent first; apply and check it out. If not properly sorting your articles in the frontend blog, then keep reading...

It happened that in Joomla 1.5.11 [so far as I've been informed] there's a lil bug forcing articles sorting on "order" instead of "latest". And here's the out commenting hack at hand:

Sftp in to path/whatever/components/com_content/models/category.php and out comment the lines as indicated below:

      if ($filter_order && $filter_order_Dir)
      {
         $orderby .= $filter_order .' '. $filter_order_Dir.', ';
      }
//       elseif($filter_order == '' && $filter_order_Dir == '')
//      {
//            $filter_order='a.ordering';
//            $filter_order_Dir='ASC';
//            $orderby .= $filter_order .' '. $filter_order_Dir.', ';
//      }   

If you've downloaded J1.5.x past this moment [see the date of this post] then just ignore it.
