PHP Warning: in /srv/html/wp-includes/class-wp-hooks.php

Hi,

I get the following error:

PHP Warning: Parameter 2 to JiscSite::advanced_custom_search() expected to be a reference, value given in /srv/html/wp-includes/class-wp-hook.php on line 288

I have updated all plugins 1 by 1 and the error still remains. The WP was also updated.

I have tried different solutions which worked before but now they don’t.
– Tried updating /wp-includes/script-loader.php function wp_default_scripts(&$scripts) to ($scripts)

PHP Version: 7.3.24
WordPress version: 5.3.2

public function apply_filters( $value, $args )

$value = call_user_func_array( $the_['function'], array($args) );

<<< Error here

Anyone successfuly solved it?

Thanks!
