Using drupal_add_feed() in template.php gives warning errors As soon as I add a call to drupal_add_feed in my theme template.php file I get this warning:


  Warning: call_user_func_array() expects parameter 1 to be a valid
  callback,   no array or string given in theme_get_registry() (line 277
  of  /var/www/example.com/includes/theme.inc).


The feed (created by Views) is valid, and the code works, i.e. it does add the meta tag. But the warning is unacceptable, obviously.

Fix? Something I'm doing wrong?
You need instal Zen and STARTERKIT theme in (...sites\all\themes).Because STARTERKIT need Zen theme to work.
