OK – this apparently has NOTHING to do w/ the vbulletin bridge – I’ve totally removed it and uploaded all new install of wordpress …
This error is happening everywhere – even when users leave comments:
Warning: call_user_func(twentyten_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home2/twcadmin/public_html/wp-includes/comment-template.php on line 1335
Warning: call_user_func(twentyten_comment) [function.call-user-func]: First argument is expected to be a valid callback in /home2/twcadmin/public_html/wp-includes/comment-template.php on line 1335
I’ve googled and searched and I’m finding tons of sites generating this error in the last few days.
DOES ANYONE KNOW HOW TO FIX THIS?
I’m experiencing the same thing. If you figured it out, I’d love to know the solution. If not, it would be nice if someone could help out.
Just found this fix on another forum post. It works:
edit this line from comments.php:
wp_list_comments( array( ‘callback’ => ‘twentyten_comment’ ) );
and change ‘tentyten_comment’ to the function name of an existing ‘comments’ function; i.e. the name of the comments function you are working on at the moment in functions.php of the theme.
or bring it back to the ’empty’ state:
wp_list_comments();
which should remove the error message.
I found the fix to this error. For some reason the coding was picking up one of the default themes that comes with wordpress that has the twentyten coding in it. I went into the default WordPress theme and pulled out the comments.php code and pasted it into my comments.php on my new custom made theme.
Bingo Bango Bongo .. worked perfectly. Here’s the coding so you don’t have to go far.

dgraydesign – I just want to thank you very much for posting your solution. I just upgraded to 3.1.1 and got the same error message wherever someone left a comment. I followed the instructions you posted and it solved the problem. 🙂
bookyeti – glad it worked for you!
if you’re doing this with custom theme based off of twentyten or a child theme of twentyten you need to then include the twentyten_comments() function from twentyten/functions.php into your functions file. It’s erroring because that function isn’t there
was having this error on all of IT Solutions blog post
It was nice being able to find this post, it fixed my issue straight away.
I’m having this same problem, except I don’t have a comments.php file. There is just comment.php and comment-template.php. The comment.php in my theme looks very different from the comments.php in the default theme. It doesn’t even have the wp_list_comments( array( ‘callback’ => ‘twentyten_comment’ ) ); line in it, so I don’t really know what to do.
I’m using a custom made theme from someone who designed it for our college newspaper last year, so I’m kind of walking into this blind. Anybody have any ideas? Thanks.
