class-theme-my-login-template.php not activating

That doesn’t work with the plugin’s classes, only templates. Which messages are shown above the title?

I’m trying to change the messages:
Please enter your username or email address. You will receive a link to create a new password via email.

I do not use usernames, only email addresses, so I need the message to indicate Please enter your email address…

Also, the title of the page says Register so the message “Register For This Site” seems redundant and thus I would change it.

All I know is where I found the messages, in the class-theme-my-login-template.php file.

How should I change them?

Thanks again.

Those are shown below the title, no? By any means:

function tml_action_template_message_filter( $message, $action ) {
    if ( 'register' == $action ) {
        $message = '';
    } elseif ( 'lostpassword' == $action ) {
        $message = 'YOUR NEW MESSAGE HERE';
    }
    return $message;
}
add_filter( 'tml_action_template_message', 'tml_action_template_message_filter', 10, 2 );
