Here is some HTML to look for:
<style>.FriendsComments table table { display:none; } .friendsComments td { height:0px; } .FriendsComments td { background-color:transparent; } .FriendsComments td td b a { display:inline; }</style>
<style>.friendsComments {display:none;}</style>
If you still don't find it, try using CTRL f and type in the word "comment" and make sure it's NOT on exact word or phrase. Then look through all the codes with the word comment in them and delete the one that says "Display none" or "Hide."
Hope that helps!
