Question

Custom Wordpress 404 page not loading, Nginx 404 page loading instead.

I’m not sure why, but my custom Wordpress 404 page will not load with an improper URL that should 404, instead, the default Nginx 404 page loads. All pages are working as expected, I just want a 404 to be my 404, not the default. I’ve tried changing my permalinks just to update them, no luck. I suspect it has to do with my sever block, any ideas?

server {
        # The below listen is moved / contained in a server block down below, controlled by CertBot.
        # Only ONE default_server is allowed.
        # listen 80 default_server;
        # listen [::]:80 default_server;

        root /var/www/porterbytes.com/html;
        index index.php index.html index.htm index.nginx-debian.html;

        server_name porterbytes.com www.porterbytes.com;

        location / {
            #try_files $uri $uri/ =404;
            try_files $uri $uri/ /index.php?$args =404;
        }

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
        }

        location ~ /\.ht {
            deny all;
        }

        location = /favicon.ico { log_not_found off; access_log off; }
        location = /robots.txt { log_not_found off; access_log off; allow all; }
        location ~* \.(css|gif|ico|jpeg|jpg|js|png)$ {
            expires 7d;
            add_header Cache-Control "public, no-transform";
            log_not_found off;
        }

Hi there @Porter,

I think that the problem is caused by this line in your config here:

        location / {
            #try_files $uri $uri/ =404;
            try_files $uri $uri/ /index.php?$args =404;
        }

The =404 pice at the end tells nginx to handle the 404 pages rather than letting your WordPress handle that.

Try removing that the =404 part, run a config test with:

nginx -t

If you get Syntax ok restart Nginx and try again.

Let me know how it goes! Regards, Bobby
