I have tried using all the patches and SVNs mentioned in this forum including

 

community.getk2.org/forum/topics/title-alias-instead-of-title

 

But still my K2 urls doesn't seem to work - they are using alias instead of title.

i have also attached the com_k2.php file i am using now.

 

and also my Tags are going to a 404 page.I think the K2 sh404sef plugin needs a serious look into

 

Thank You
