desireeM	Background of the issue: WPML 4.6.13 sitepress-multilingual-cmsclassesrequest-handlingclass-wpml-language-per-domain-sso.php You have this code: `if ( ! apply_filters( 'send_auth_cookies', true ) ) {` But in wp-includes/pluggable.php there is: `if ( ! apply_filters( 'send_auth_cookies', true, $expire, $expiration, $user_id, $scheme, $token ) ) {` If any plugin add_filter on "send_auth_cookies" hook, e.g. ``` add_filter( 'send_auth_cookies', 'are_cookies_allowed', 10, 4 ); function are_cookies_allowed( $filterable, $expire, $expiration, $user_id ) { ``` The site doesn't work and you get a fatal error. You need to pass all args like WP core when re-using WP core hooks in your plugin. Symptoms: Fatal error because WPML send_auth_cookies filter has too few arguments. The site doesn't work and you get a fatal error. Questions: Fix this

desireeM	In PHP 7.4+ (including 8+) we get: Fatal error: Uncaught ArgumentCountError: Too few arguments to function my_callback(), 1 passed in ....php on line x and exactly 4 expected in ... We get this whenever this class is loaded - it seems only if language per domain SSO is used from the class name.

Bruno Kos Supporter Languages: English (English ) German (Deutsch ) French (Français ) Timezone: Europe/Zagreb (GMT+01:00)	This is escalated to WPML developers team. I will keep this thread updated, but possibly the solution will be that we use if ( ! apply_filters( 'send_auth_cookies', true, $expire, $expiration, $user_id, $scheme, $token ) ) { return; } in our code.

desireeM	Exactly that's the solution
