Nginx returning blank HTML pages with php-fpm

Question

I'm using php-fpm through Nginx.

My nginx.conf can be found here: http://pastebin.com/Nu9iD8Km
It includes a file found here: http://pastebin.com/ece4cwXF
My php-fpm.conf can be found here (all the options omitted are the default): http://pastebin.com/70fBE30E
My fastcgi_params file is similar to the default, but adds this line, following a recommendation on the web: fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

I keep getting blank pages instead of PHP scripts, but static stuff loads fine. What's weird is that I'm not getting 404 errors - my browser tells me that the status code is 200 OK.

Neither nginx or php-fpm's logs turn up anything interesting. What may be causing this?

How can I fix this?

Answer 1

My php section looks like this:

 location ~ \.php$ { include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_pass unix:/dev/shm/php-fastcgi.socket; } 

My listen directive in php-fpm.conf this:

listen = /dev/shm/php-fastcgi.socket 

Could you also provide your php-fpm.conf? If the error still exists, please enable logging in fpm and provide fpm logs:

php_admin_value[error_log] = /var/log/fpm-php.www.log php_admin_flag[log_errors] = on 

Answer 2

I had similar issue - blank pages without warning - short_open_tag = On solved the problem. Check php.ini short_open_tag is it ON or OFF? If you use shortcuts like <?=$test?> or if you open tags with just <? it should be set to ON.
