How to disable default password reset email

Dzień dobry (it’s nearly the only Polish I know)

That sounds like a lot of fuss to address a minor error. My inclination is to address the root cause instead of blocking one email and recreating virtually the same. My advice is to first undo what you have now and restore the default behavior that is causing the problem.

Next, add code to a child theme or custom plugin that hooks the ‘retrieve_password_message’ filter. Your callback function is passed the default email message body. Fix the offending link by use of PHP string manipulation functions like str_replace() or preg_replace(). Return the revised message and the user will receive a functioning link in their mail client.

Thank you. It works.

This is what I added to functions.php (for the benefit of others):

add_filter("retrieve_password_message", "mapp_custom_password_reset", 99, 4);

function mapp_custom_password_reset($message, $key, $user_login, $user_data )    {

$message = "Otrzymali?my pro?b? o nowe has?o do nast?puj?cego konta: " . sprintf(__('%s'), $user_data->user_email) . "

Je?li to pomy?ka, zignoruj tego emaila. Aby uzyska? nowe has?o, przejd? na t? stron?:

Je?li masz jakie? pytania, to napisz do nas na adres [email protected]
