PHP Warning when manually adding orders from BO

[zanpo]

Hello, 

 

Every time I manually add an order from the Back Office, I get this error in my error.log. This error appears just after I search for my product and I click on the 'Add to cart' button from the BO:

 

2015/10/30 13:23:38 [error] 5529#0: *106632 FastCGI sent in stderr: "PHP message: PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/admin/mydomain.com/public_html/controllers/admin/AdminCartsController.php:477) in /home/admin/mydomain.com/public_html/classes/controller/AdminController.php on line 1787" while reading upstream, client: xx.xx.server.ip, server: mydomain.com, request: "POST /admin123/index.php?controller=AdminCarts&token=78186f7798400bf4816694357c39fc55 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "mydomain.com", referrer: "http://mydomain.com/admin1123/index.php?controller=AdminOrders&addorder&token=2d03183d134e3005f63eff6c3d08b75c"

 

I have PHP 5.6.14 with nGINX and running Prestashop 1.6.1.1

 

As I see the error is from line 477 in AdminCartsController.php, but I have no idea what is wrong with that line:

 

echo Tools::jsonEncode(array_merge($this->ajaxReturnVars(), array('errors' => $errors)));

I can successfully add the order with this error, but I'm not sure how it affects the site. Can anybody help?

 

Thanks

I have the same problem and I have Nginx too.

this usually means your nginx is not properly configured, and that the proxy buffer is too small or that the timeout settings are too low.

Thanks for the tip. I modified the proxy setting. The error still appears in my error.log Here are my current settings for proxy buffers and timeout, how big should I put them? I think this is big enough, no?

proxy_connect_timeout   90;
proxy_send_timeout      90;
proxy_read_timeout      90;
proxy_buffers           16 512k;
proxy_buffer_size       512k;
proxy_busy_buffers_size 512k;

send_timeout                    30;
keepalive_timeout               30;
fastcgi_read_timeout            125;
fastcgi_buffers                 6 512k;
fastcgi_buffer_size             512k;

i can't tell you what the correct settings are, but if you are still receiving the same error, then the settings are still not appropriate

I'm using Apache and get this error when adding orders:

Any ideas?
