 * Hi,
 * I am receiving this error sporadically throughout my site.
 * ‘Warning: call_user_func_array() expects parameter 1 to be a valid callback, 
   function ‘omega_default_footer_insert’ not found or invalid function name in /
   vhost/vhost14/f/o/o/foodserve.net/royallondon/wp-includes/plugin.php on line 
   213′
 * Any ideas?
 * Thanks,
 * Maxine

 * It was to do with the copy-write code. All sorted now.

 * Hi Maxine,
    Glad to hear it fixed. You might have customized the theme as I don’t
   see any error on my install.
