 * So this is my first time posting, sorry if i dont include all that is needed 
   here. i have search these forumns, google, and bing for an answer to this but
   i can not find anything. Currently the comments on my post are displaying this
   message:
 * Warning: call_user_func(art_comment) [function.call-user-func]: First argument
   is expected to be a valid callback in /home/airrifle/public_html/wp-includes/
   comment-template.php on line 1242
 * This just started to happen on my test blog. My companies main blogs are fine.
   I believe it is the spell check plugin i have installed. because when i deactived
   it and removed the 2 lines of codes on my comments.php file. the comments then
   displayed the original messages. Thats all fine and dandy but i want the spell
   checker plugin to remain and also i am worried about my main blog for my company
   running into this same fate. the site is airriflesonline.com. There is nothing
   on there but a few test posts as i am just using to test new plugins and features.
 * in the comments template file it is as followed
    1241 if ( !empty($args[‘callback’])){
   1242 call_user_func($args[‘callback’], $comment, $args, $depth); 1243 return;

 * Have you tried switching to the default theme to rule out any theme-specific 
   problems?

 * Just tried and the comments are still showing that error message. i have also
   tried pulling the templates from the active blog and switched out them out, but
   still the same message. And i also put the original WP files in there as well

 * OK – try:
 * – deactivating **all** plugins to see if this resolves the problem. If this works,
   re-activate the plugins one by one until you find the problematic plugin(s).
 * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F)
   by FTP or phpMyAdmin. Sometimes, an apparently inactive plugin can still cause
   problems.
 * – re-uploading the wp-admin and wp-includes folders from a **fresh** download
   of WordPress.

 * For these who has theme-specific problems with call_user_func() Warning and comments:
 * – check if your **functions.php** has **all** the required functions that comments.
