CODING ERROR WHEN INSTALLING

I installed this theme: Now I have this Code at the bottom of my page: Fatal error: Uncaught Error: Call to undefined function get_the_privacy_policy_link() in /www/doc/www.inkanotes.com/www/wp-content/themes/divin-pro/inc/template-tags.php:421 Stack trace: #0 /www/doc/www.inkanotes.com/www/wp-includes/class-wp-hook.php(298): divin_footer_content('') #1 /www/doc/www.inkanotes.com/www/wp-includes/class-wp-hook.php(323): WP_Hook->apply_filters('', Array) #2 /www/doc/www.inkanotes.com/www/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 /www/doc/www.inkanotes.com/www/wp-content/themes/divin-pro/template-parts/footer/site-info.php(14): do_action('divin_credits') #4 /www/doc/www.inkanotes.com/www/wp-includes/template.php(690): require('/www/doc/www.in...') #5 /www/doc/www.inkanotes.com/www/wp-includes/template.php(647): load_template('/www/doc/www.in...', false) #6 /www/doc/www.inkanotes.com/www/wp-includes/general-template.php(167): locate_template(Array, true, false) #7 /www/doc/www.inkanotes.com/www/wp-content/themes/divin-pro/footer.php(45): get_template_part('template-parts/...', 'i in /www/doc/www.inkanotes.com/www/wp-content/themes/divin-pro/inc/template-tags.php on line 421 This is obviously a coding error. Can you fix this for me.
