Current K2 v2.6.7 is not full support Sef url replacements to some languagues (ex: vietnamese) ! K2 v.2.6.3 full support SEF URL

admin suggest using other ext, I do not like at all, actually if using other ext I will return using Joomla Content not using K2. 


Go to Parameters > select Advanced tab
