Upload Error: client intended to send too large body

If you are using Nginx and are unable to upload files exceeding 1MB or so (most common) and get your error log shows “client intended to send too large body”, then here is the fix.

Edit your Nginx configuration file (which on Debian/Ubuntu will be found at /etc/nginx/nginx.conf) and edit the setting for client_max_body_size to something you can live with. If there is no line for it, add this line:

client_max_body_size 5M;

Obviously, replace 5M (for MB) with a number that makes you happy if your upload is larger.
