Messed up functions.php

Hi, Hope someone can help me!
I messed up my functions.php file. Even though it seems to me that right now it’s just the way before I tried some changes. But yet it doesn’t work
This is the end part of the code, where the error is supposed to be.

/**
 * Layerslider API
 */
function avada_layerslider_ready() {
	if( class_exists('LS_Sources') ) {
		LS_Sources::addSkins( get_template_directory().'/framework/ls-skins' );
	}
	if( defined( 'LS_PLUGIN_BASE' ) ) {
		remove_action( 'after_plugin_row_' . LS_PLUGIN_BASE, 'layerslider_plugins_purchase_notice', 10, 3 );
	}
}
add_action( 'layerslider_ready', 'avada_layerslider_ready' );
