 * Hi there, it was working before not sure what happened.
 * Plugin causes error when attempting to view the cart and user not logged in

 * I discovered the problem is related to having a large cart shared

 * I fixed the issue but I believe my settings may be overkill
 * Within the php-fpm pool for the domain I added these lines
    fastcgi_buffers 16
   64k; fastcgi_buffer_size 64k;

 * Hi,
 * Love the idea of this plugin, but have just run into an issue, similar to the
   above.
 * When adding more than two items to a cart and sharing, the receiver gets the 
   email and link, but arrives at an empty cart?
