   After updating from 2.1.1 to 2.5.1 i get this error on my posts:

   Fatal error: Class 'CoAuthorsIterator' not found in single.php on line 143

   I have an author box on my posts and i am using an iterator to show coauthors.

   Any help please?

   This is my code
   

   <?php $i = new CoAuthorsIterator(); ?>
   <div id="about_the_author">
   <div class="header"><h5>Autore</h5></div>
   							<hr/>
   <?php while($i->iterate()){ ?>
   <div class="thumb">
   <?php echo get_avatar( get_the_author_meta('user_email'), '100', '' ); ?>
   </div>
   <div class="description">
   <strong><?php the_author_posts_link(); ?></strong><br/>
   </div>
   <div class="description">
   <p><?php the_author_meta('description'); ?></p></div>
   <?php } ?>

   It's always a good idea to use things like function_exists and class_exists when using code from external plugins. In your case, something like:

   if( class_exists( 'CoAuthorsIterator' ) ) {
       $i = new CoAuthorsIterator();
       // rest of your code
   } else {
       // add a fallback here
   }
