Why does this 'save_post' hook not trigger the function?
Given this code in functions.php:
add_action('save_post', 'save_custom_data');
function save_custom_data() {
  error_log('Saving data');
}

Why might 'Saving data' not appear in the error log when a post is saved?
Wordpress
add_action('save_post', 'save_custom_data');
function save_custom_data() {
  error_log('Saving data');
}
AThe function name is misspelled in the add_action call.
BThe error_log function is disabled in the server configuration.
CThe 'save_post' hook passes parameters, but the function does not accept any, causing it not to run.
DThe 'save_post' hook only triggers on pages, not posts.
