Thank you so much @davelavoie it's working perfectly.
Awesome! Thanks.
@davelavoie Thank you very much! It save me a lot of time !
Very useful! Thank you! I think remove_class_action should return remove_class_filter as latter returns trueif successful. So it should read return remove_class_filter($tag, $class_name, $method_name, $priority);
@ouun yes i agree, updated the gist to reflect that, thanks!
Thanks a lot, struggled to remove an action with a class name and your functions worked straight away!
Hi all,
From WP 5.5, there seems to be an issue when removing anonymous functions that could cause an Uncaught Error: Closure object cannot have properties in /var/www/html/wp-includes/class-wp-list-util.php:115.
I have seen a related issue here: senlin/so-clean-up-wp-seo#88
Where a new filter to this function was added on this commit:
senlin/so-clean-up-wp-seo@aa061ca
function remove_class_hook( $tag, $class_name = '', $method_name = '', $priority = 10 ) {
global $wp_filter;
$is_hook_removed = false;
if ( ! empty( $wp_filter[ $tag ]->callbacks[ $priority ] ) ) {
$methods = array_filter(wp_list_pluck(
$wp_filter[ $tag ]->callbacks[ $priority ],
'function'
), function ($method) {
/**
* Allow only array & string notation for hooks, since we're
* looking to remove an exact method of a class anyway. And the
* method of the class is passed in as a string anyway.
*/
return is_string($method) || is_array($method);
});
$found_hooks = ! empty( $methods ) ? wp_list_filter( $methods, array( 1 => $method_name ) ) : array();
foreach( $found_hooks as $hook_key => $hook ) {
if ( ! empty( $hook[0] ) && is_object( $hook[0] ) && get_class( $hook[0] ) === $class_name ) {
$wp_filter[ $tag ]->remove_filter( $tag, $hook, $priority );
$is_hook_removed = true;
}
}
}
return $is_hook_removed;
}
Buenas tardes al Equipo Lucas Ferreira. Gracias por la atención. Yo hablo
otros idiomas, el principal el español, el segundo más hablado en el mundo.
Y si continuamente voy a recibir esta información en inglés, pues no estoy
dispuesto por mi parte que sea así. Por tanto no deseo recibir más correos
en inglés, y si no hay solución prefiero dar baja a la suscripción. Y no
manden más correos así.
Gracias de nuevo y buen día.

All depends on what you're trying to remove. You need to determine when the
add_actionis being called (that you want to remove), and make sure you're calling your code to remove it, AFTER that point ... either with a higher priority to another action, or after that code has been ran to add that action/filter
