I just recently (a few hours ago) got wordpress 2.0.5 up and running. I then put the Skippy plug in for gravatars and after an hour of no joy got it working. Then I posted and left a test comment. It all looked great.
But these same comments are not working when I am not logged in and viewing from "preview mode" when editing a post. Otherwise nothing shows up down below. I am relatively certain it must be from using the gravatar edited comment.php
this entire code is at http://wordpress.pastebin.ca/303574 I am a total newb to php and was so so excited to get it working at first! I hope someone can help!
Oh and if you need to experience my lack of comments: http://www.send-rose-flower.com/flowerblog/
