Products order in frontend don´t work after updating to VM 2,0,16

[Roffer]

I can´t set the order of product in frontend after updating VM to 2,0,16.  I have Joomla 2,5,8 and PhP 5,3,3

If I try change the order in frontend I get a page whit the text: "Not Found  The requested document was not found on this server." ??

I can´t reorder the product in backend either

Check the server error logs as "Not Found  The requested document was not found on this server" could be related to a 500 error and a report of the cause should be logged.
