Hi everyone,

I am using nginx 1.4.1 and php-fpm 5.3.25.

Everything is fine except when I uploading files to server.

I have a Discuz! x3(a forum system) and when I post threads, except  
attachment everything is fine, but when I add a small files(such as 30k  
rar,jpg or else), nginx give me a 500 error.

I checked the nginx/site error, but have no usefule information. nginx  
only  
tell me a got an 500 error, but didn’t tell me why.

I tried to increase the fast\_cgi parama:

fastcgi\_connect\_timeout 300;  
fastcgi\_send\_timeout 300;  
fastcgi\_read\_timeout 300;  
fastcgi\_buffer\_size 1024k;  
fastcgi\_buffers 32 64k;  
fastcgi\_busy\_buffers\_size 1500k;  
fastcgi\_temp\_file\_write\_size 1800k;

But still the same.

So, please help me for solve this problem, I wonder where can I got the  
error message?

Thank you.

If the 500 is returned by nginx, there should be an explanation in  
error log.

If there is nothing in error log - this suggests the 500 response  
is generated by php, and you have to dig into the php code to see  
what happens there.
