Played around with .php file and my website stopped working

I think something went wrong here:

 
 
 
$avia_config['color_sets'] = array(
    'header_color'      => 'Logo Area',
    'main_color'        => 'Main Content',
    'alternate_color'   => 'Alternate Content',
    'footer_color'      => 'Footer',
    'socket_color'      => 'Socket'
 );
 
 

/*
 * add support for responsive mega menus
 */
 
add_theme_support('avia_mega_menu');

/*
 * deactivates the default mega menu and allows us to pass individual menu walkers when calling a menu
 */
 
add_filter('avia_mega_menu_walker', '__return_false');

Im desperate. I dont have a backup and I dont know anything about coding. I wish I just could revert my changes, but I cant!
