 * I get this message when I try to comment on my post, logged in or out, doesn’t
   matter:
 * `Warning: call_user_func(twentyten_comment) [function.call-user-func]: First 
   argument is expected to be a valid callback in /home/erisdesi/public_html/wp-
   includes/comment-template.php on line 1308`
 * And I’m not so hot with the PHP yet. How do I fix?

 * Upon further investigation, there is no mention of `twentyten_comment` on line
   1308 of `comment-template.php`. Does wordpress cache posts somehow, or is it 
   possible that it’s being cached by a plug-in or something else? I also have the
   question listed on stackoverflow, if any information posted there helps…

 * Solved. Read my last comment on the above link.

 * I’m trying hard to follow the solution here (and on stackoverflow) but am having
   no luck.
 * All comment.php files appear to be up to date in twentyten and child theme.
 * I’ll keep searching I guess.
