help! our post arrangement is messed up after messing with templates

[Chicago_VLNU_4s]

ok, so i tried to install this... All Media hack

and what i got from the install notes, was to REPLACE what it told me to look for, with the bottom input field code. but i think i had to add it.. anyways, now our post are f*cked up! when i make a post in quick post, i press "post quick reply" and it doesnt do anything. it'll say loading, then when its done, you dont see the reply.. and when u refresh, its in the wrong place.. like all the way at the top of the replies or somewhere in the middle. and if u press post a second time, for some reason, it seems to make duplicates of every post in the thread. what is goin on! can i get the orginal template codes to see if it'll fix it for

editor_toolbar_on Template:
postbit_attachment Template:
postbit_quickedit Template:
showthread_quickreply Template:

someone please help out
