I set the following command for cron on a shared server.
(All the Drupal files are under /public_html)
This commend seems to be working but I get the following error
PHP Warning: Cannot modify header information - headers already sent by (output started at /home/public_html/sites/default/settings.php:1) in /home/public_html/includes/bootstrap.inc on line 1163
Sorry, has been banned.
Am I missing something?
