Hi Greyhare,

According to WordPress guidelines add_shortcode() has been removed. So we have changed that code according to WordPress guidelines. So the above code will work. It needs code customization.

Please remove this code
$output = ‘<div class=”copyright”>’.’Copyright © [the-year] [site-link] | Website by: Greyhare Design ‘.'</div><!– .copyright –>’;

and add this code
$output = ‘<div class=”copyright”>’.__( ‘Copyright ©’, ‘attitude’ ).’ ‘.attitude_the_year().’ ‘ .attitude_site_link().’ | ‘ . ‘ ‘.__( ‘Website by: Greyhare’, ‘attitude’ ).'</div><!– .copyright –>’;
echo $output;

Thank you!
