What is "/2011-10-05-10-03-32/2011-08-15-20-38-32/" in URL adress. How can I this eliminate? (K2categorie)

These dates are generated when the "External URL" menu item type is used - if you changed the external url menu items to other menu item types you should remember to specify another alias for these menu items.

Thank You.
