I am trying remove the following:

$wp_user = wp_signon(
    array(
        'user_login' => $mepr_screenname,
        'user_password' => $mepr_user_password,
    ),
    MeprUtils::is_ssl()
); 

from function process_reset_password_form() using a filter function in the child theme but not getting any way.

Here is the complete code .php

Any help is appreciated. Thanks
