How to enable uploads of files larger than 2MB to your WordPress-site (using NGINX)

I. Configure PHP-FPM

We start by editing the PHP-FPM configuration file php.ini found here on Debian Buster (replace “7.3” with whatever version you’re running).

nano /etc/php/7.3/fpm/php.ini

Add the following lines at the very end of the file. (Check out what this actually does on

upload_max_filesize = 100M post_max_size = 100M

Reload the PHP-FPM service.

systemctl reload php7.3-fpm
Code language: CSS (css)

II. Configure NGINX

Now we configure the NGINX website configuration file on the host (note: not on the reverse proxy).

nano /etc/nginx/sites-available/

So that it looks something like this. (Find out what the added line does here:

server { listen 80; root /var/www/html/; server_name; location / { index index.php index.html; try_files $uri $uri/ /index.php?$args; } location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/run/php/php7.3-fpm.sock; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; client_max_body_size 100M; # Add this line! } }
Code language: PHP (php)

Now we check if we did anything wrong and if not, reload the NGINX service.

nginx -t systemctl reload nginx

And that should do it. Now I can finally upload those huge images SEO:s love.
