Also, if you are using our theme then make sure to create a child theme and paste this code in child-theme function.php.
Hi,
Currently on Version 4.3.2 the filter has changed a lot so you can use the next code inside functions.php to remove the flag link if the code above doesn’t work:
function custom_post_actions($actions)
{
return array_filter($actions, function ($action) {
return $action[‘cb’] != ‘flag’;
});
}
add_filter(‘ap_post_actions’, ‘custom_post_actions’);
