Blank Page: wordpress on nginx+php-fpm

Good day.

While this post discusses a similar setup to mine serving blank pages occasionally after having made a successful installation, I am unable to serve anything but blank pages. There are no errors present in /var/log/nginx/error.log, /var/log/php-fpm.log or /var/log/nginx/us/sharonrhodes/blog/error.log.

• Wordpress 3.0.4


• nginx 0.8.54


• php-fpm 5.3.5 (fpm-fcgi)


• Arch Linux

php-fpm.conf:

Answer

By default the Nginx source does not define SCRIPT_FILENAME in the fastcgi_params file, so unless the repo you installed Nginx from does that you need to do it yourself.

Check if the following line is in your fastcgi_params file:

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;

and if not then add it.
