Wordpress on forge upstream sent too big header while reading response header from upstream

Posted 2 years ago by eddieace

Hi I have a wordpress site running on forge. I get this error.

502 Bad Gateway

From log:

017/03/07 09:40:30 [error] 12586#12586: *13909 upstream sent too big header while reading response header from upstream, client: 46.59.124.52, server: example.com, request: "GET /wp-admin/post.php?post=123&action=edit HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.1-fpm.sock:", host: "example.com", referrer: "http://ecample.com/wp-admin/edit.php?post_type=page&orderby=title&order=asc"

Online I have found a few solutions.

The first one is this but the problem is that I don't know where to add it. I have tried both in etc/nginx/nginx.conf and in the location block in sites-available.

fastcgi_buffers 16 16k; 
fastcgi_buffer_size 32k;

Any clues on how to fix this?
