delete theme info in socket / copyright

This is the code in my footer.php:

//copyright
$copyright = do_shortcode( avia_get_option(‘copyright’, “© “.__(‘Copyright’,’avia_framework’).” – “.get_bloginfo(‘name’).”“) );

// you can filter and remove the backlink with an add_filter function
// from your themes (or child themes) functions.php file if you dont want to edit this file
// you can also just keep that link. I really do appreciate it ;)
$kriesi_at_backlink = kriesi_backlink(get_option(THEMENAMECLEAN.”_initial_version”));

//you can also remove the kriesi.at backlink by adding [nolink] to your custom copyright field in the admin area
if($copyright && strpos($copyright, ‘[nolink]’) !== false)
{
$kriesi_at_backlink = “”;
$copyright = str_replace(“[nolink]”,””,$copyright);
}

if( $footer_widget_setting != ‘nosocket’ )
{

?>
