 * `Fatal error: Call to undefined method stdClass::wp_head() in /home/lenoid/public_html/
   wp-content/plugins/parallel-load/parallel-load.php on line 65`
 * Appears to be some problem referencing changes to wp_head() WordPress function.

 * If you mean this one [http://wordpress.org/extend/plugins/parallel-load/](http://wordpress.org/extend/plugins/parallel-load/)
   then that plugin may simply be too dated (last updated 2009-4-2).
 * Since WordPress 2.7.1 there have been many changes and that one may have just
   fell by the wayside.

 * Yep, I figured it was out-dated. Parallel loading sounded like a great idea for
   my site’s JavaScript files.
 * I’ll mark this topic as ‘resolved’. Thanks.
