If you want to change the link that appears at the login modal "Or Create an Account" to your own register page, do the following:

  1. Go to wp-content/themes/kleo at your hosting file manager or ftp
  2. At the folder page-parts, find the file general-popups.php, copy it
  3. Now go to wp-content/themes/kleo-child
  4. Create the folder page-parts and paste the file inside
  5. Edit the file
    Find
COPY CODE
<p>
    <em><?php esc_html_e( "or", 'kleo_framework' );?></em>&nbsp;&nbsp;&nbsp;&nbsp;
    <a href="<?php if (function_exists('bp_is_active')) bp_signup_page(); else echo get_bloginfo('url')."/wp-login.php?action=register"; ?>" class="new-account">
        <?php esc_html_e( "Create an account", "kleo_framework" ); ?>
    </a>
</p>

Replace with

COPY CODE
 <p>
                    <em><?php esc_html_e( "or", 'kleo_framework' );?></em>    
                    <a href="YOUR URL" rel="nofollow">
                        <?php esc_html_e( "Create an account", "kleo_framework" ); ?>
                    </a>
                </p>
