Hello Simon,
You will need to edit your footer.php file in order to edit anything in the footer. You can do that two ways: (1) opening the editor in WordPress and selecting footer.php OR (2) Use a FTP client and edit your footer.php that way.
You will need to be look for this specific line of code:
<div class="copyright col-lg-12">
<span class="pull-left"><?php printf( __( 'Copyright © %s %s. All Rights Reserved.', 'arcade' ), date( 'Y' ), ' <a href="' . home_url() . '">' . get_bloginfo( 'name' ) .'</a>' ); ?></span>
<span class="credit-link pull-right"><i class="fa fa-leaf"></i><?php printf( __( 'Designed by %s.', 'arcade' ), '<a href="https://themes.bavotasan.com/">bavotasan.com</a>' ); ?></span>
</div><!-- .col-lg-12 -->
</div><!-- .row -->
</div><!-- #footer-content.container -->
</footer><!-- #footer -->
</div><!-- #page -->
<?php wp_footer(); ?>
</body>
</html>
The “Pull Right” part of the code is the where your copyright and legal information goes and the “Pull Left” is the theme credit link (and if you haven’t bought the theme you should definitely leave this)! Hope this helps a little! ??
P.S – Make sure you are making changes to a child theme rather than the theme directly! If you edit the files directly, when you update your changes will be erased!
