 * When I attempt to make any update to an existing post, I get the following errors:
 * Warning: call_user_func(extract_terms::update_taxonomy_count) [function.call-
   user-func]: First argument is expected to be a valid callback in /home/woodpeck/
   public_html/wp-includes/taxonomy.php on line 1769
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/woodpeck/public_html/wp-includes/taxonomy.php:1769) in /home/woodpeck/
   public_html/wp-includes/pluggable.php on line 865
 * When I go back to view the post, the changes are there but they do not display
   on my site and the last update date shows the original post date.

 * I found the problem.
 * It was a plugin that I was using (Related Widgets Version 2.2.2 By Denis de Bernardy).
 * I deactivated the plugin and the problem stopped, I activated the plugin and 
   it would not allow updates, I deactivated the plugin and am able to update posts.
