# Debugging cron tasks

 * How could I debug cron task run by internal [cron functions](http://codex.wordpress.org/Category:WP-Cron_Functions)?
   My cron task is not firing and I suppose some functions are not declared yet 
   when cron hook takes place.
 * It would be great if I can store the errors into some log file? Any ideas? Thanks.
 * I used [Core Control](http://wordpress.org/extend/plugins/core-control/) plugin
   to see if everything is all right. The _my\_task\_hook_ and hooked function too,
   the “due time” is changing…so something else must be wrong.

 * I am using the functions `category_exists` and `post_exists` which are declared
   for “wp-admin” only. This was the problem.
 * I found out the easiest way to debug cron in WordPress is add your function to
   this hook: `add_action( 'sanitize_comment_cookies', 'your_cron_function' );` 
   because `wp_cron` function is also executed in this action hook. You will see
   errors outputted (if there are any) after doing this when you reload your front-
   end page.
