I have noticed a strange problem since upgrading to Joomla 3.3.6.
In the Article Manager, the Ordering column no longer works - no arrows, no numbers, no drag-n-drop icons. This is also the same for Featured Articles. However, Categories works fine.
I have searched online but can't find anyone with the same problem, so I think it may be one of the plugins I have installed (could that cause such a problem?).
I just wondered if anyone else has experienced the same thing or if anyone has any other suggestions...

to open the browser console, click on theConsole
tab, refresh the page and see if there are any errors. It works fine for me so I'm thinking you might have a custom script causing issues
