Forum Threads appear in random order
 

I upgraded my forum from vb3.8 to vb4 and for some reason the threads are displayed according to thread title and not the recent one first.. so when a user posts a new thred depending on the thread title its showing in the 3rd or fourth page of the forum!!

the only way i could show them recent first if i select from the thread sorting menu.. I tried to find the setting in Admin CP where i could control that but i was unable to find..

Please Help.
