More Information

Prior to Version 4.7

  • You can’t call this function from within the hook you would like to remove actions from. For example adding an action to wp_footer that calls remove_all_actions('wp_footer') will cause an infinite loop condition because the while loop suddenly doesn’t have a next value. In WordPress 3.8.1 you’ll get a warning message like:
    Warning: next() expects parameter 1 to be array, null given in wp-includes/plugin.php on line 431
  • You’ll just need to hook into a hook that’s called before the hook you wish to clear is called.

Since Version 4.7, these limitations have been addressed. Please refer to
