I’m trying to get W3 Total Cache to rewrite URLs to minified files. I’ve tried every tutorial I could find but I don’t seem to be able to get it right. I keep getting a W3 Total Cache error saying this:
It appears Minify URL rewriting is not working. If using apache, verify that the server configuration allows .htaccess. Or if using nginx verify all configuration files are included in the main configuration fail (and that you have reloaded / restarted nginx).
My config files for nginx are as follows:
nginx.conf in /etc/nginx/
user nginx;
worker_processes 2;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
multi_accept on;
}
http {
include mime.types;
default_type application/octet-stream;
access_log off;
sendfile on;
keepalive_timeout 20;
client_max_body_size 15m;
upstream php {
server unix:/dev/shm/php-fpm-www.sock;
}
include /etc/nginx/conf.d/default.conf
}
This file links to /etc/nginx/conf.d/default.conf:
server {
server_name mydomain.com www.mydomain.com;
listen 8080;
root /var/www/;
index index.php index.html index.htm;
include /var/www/nginx.conf;
include /etc/nginx/conf.d/wp.conf;
}
This file itself links to /etc/nginx/conf.d/wp.conf which looks as follows:
error_page 404 = @wordpress;
log_not_found off;
location / {
try_files $uri $uri/ /index.php?args;
}
rewrite /wp-admin$ $scheme://$host$uri/ permanent;
location @wordpress {
fastcgi_pass php;
fastcgi_param SCRIPT_FILENAME $document_root/index.php;
include fastcgi_params;
fastcgi_param SCRIPT_NAME /index.php;
}
location ~ .php$ {
fastcgi_max_temp_file_size 1M;
fastcgi_connect_timeout 60;
fastcgi_send_timeout 180;
fastcgi_read_timeout 180;
fastcgi_buffer_size 128k;
fastcgi_buffers 4 256k;
fastcgi_busy_buffers_size 256k;
fastcgi_temp_file_write_size 256k;
fastcgi_index index.php;
fastcgi_pass php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
try_files $uri @wordpress;
}
/etc/nginx/conf.d/default.conf also links to the nginx.conf file W3 Total Cache created in my WordPress root folder, which looks as follows:

During copy pasting from nano in my terminal some lines weren’t entirely in screen, but these are all standard W3 Total Cache settings, I haven’t touched them. They should be ok.
I’ve got my server setup with nginx on port 8080, varnish on port 80, php5-fpm and MySQL. If anyone can help me out on this, that would be amazing. If you need more info, config files, etcetera, please let me know.
Create a file specifically for W3 Total Cache configuration for your site, in a location Nginx/PHP-FPM can write to. Include this file in your site’s Nginx server configuration. Then on the General Settings page, under Miscellaneous provide the full path to this file in the “Nginx server configuration file path” field. W3TC will then know to write any Nginx rules it needs to this file.
Make your W3TC settings changes to reflect the configuration you’d like. Once you’re happy with the settings, reload Nginx. Your W3TC configuration should now be working properly.
Just disable javascript minification. I did it for my site and it worked.
