I am trying to:
View the page

I visited this URL:
hidden link

I expected to see:
Normal page
Instead, I got:
The following warning on the top of the page:
Warning: Missing argument 2 for {closure}(), called in /www/trooptravel_653/public/wp-includes/class-wp-hook.php on line 300 and defined in /www/trooptravel_653/public/wp-content/themes/TroopTravel/functions.php on line 163

I have the following code starting on line 163 of functions.php:
add_filter('get_layout_id_for_render', function($layout_id, $slug){

global $post;

if( null !== $post && $post->post_type === 'trip' && isset($_GET['cred-edit-form']) ){
$layout_id = '9540';
}
return $layout_id;
} );

Hi Leonard,

Thank you for contacting Toolset Support. I have been checking the issue then suddenly the error goes away from the page. Looks like you may have resolved it already, please advise further.
