I use WP 2.6.3 Cutline 3-column. http://www.whahappen.com
I have a similar problem. I attempted to show comments at the bottom of each post by accurately following directions from: http://www.flisterz.com/2008/06/02/wordpress-display-comments-on-main-page/
It works great except for a couple of things. 1) When the comments show, my right sidebar disappears. And 2) I have a default of showing 3 posts on my homepage, but with comments showing, it drops to only two (I don’t know if that means anything, but having only two posts on the front is not that big a deal, just thought I’d mention that it happens along with the disappearing side bar.)
Help a sister out? Thanks.
