i'm facing a problem with nginx rewrites after i migrate my Magento website from Apache to Nginx!
When i add a product to the cart and i press the button Place the order is giving me 500 internal server error !
I opened my logs and i can see this error message :

2017/05/26 13:03:39 [error] 48314#48314: *4022 could not find named location "@handler", client: 81.149.36.86, server: abcsports.co.uk, request: "GET /index.php/checkout/onepage/ HTTP/1.1", host: "www.....", referrer: "http://www........"

My conf file is looking like that :

 listen 80;
 server_name abcsports.co.uk;

I looked everywhere on the internet and i read a lot of things but didn't find the solution ! I would appreciate any help !
Thank you !

(1) This configuration file is derived from your file and is created with the assumption that you want to force SSL on your primary domain, abcsports.co.uk. This is recommended.

(2) I moved the subdomains, "media.abcsports.co.uk, skin.abcsports.co.uk, and js.abcsports.co.uk" into separate server blocks. By default, SSL is not forced for these subdomains, but you could enable the redirections as instructed in the configuration file. Ensure that the SSL certificates for abcsports.co.uk is applicable to the subdomains before activating the SSL block for the subdomains.

(3) There could be errors. Use the error log to debug them.

(4) Backup the current vhost file because using this one. You can do this during a low traffic period.
