403 Forbidden error nginx

Issue was resolved by commenting the code that was requesting the jquery file from www.jquerye.com site. But as that site is expired the jquery link too which was giving 403 Forbidden error.

I found that piece of code in themes/themename/framework/functions/init.php file with cURL requests. I have commented the last line which was adding to wp_head add_action('wp_head', 'insert_jquery_slider'); and issue got resolved.
