Hello DenisCGN,

Please navigate to WPUF/class/admin-form.php on line 520. here you see the line
$restrict_message = __( "This page is restricted. Please Log in / Register to view this page.", 'wpuf' );

in function
function form_settings_posts() {

Replace the text between the double quote:
This page is restricted. Please Log in / Register to view this page.

by

<a href="<?php echo get_permalink( wpuf_get_option( 'reg_override_page', 'wpuf_profile' ) ); ?>" >Registration</a> / <a href="<?php echo wp_login_url(); ?>" title="Login">Login</a>

for registration and login page. if you checked Registration link override option and select registration option from adminPanel > User Frontend > Settings > Profile

by

<a href="<?php echo wp_registration_url(); ?>" title="Register">Register</a> / <a href="<?php echo wp_login_url(); ?>" title="Login">Login</a>
