Nginx and Panel configuration problem

[invasoria]

I’ve been having some trouble with a Kirby + Nginx setup. The project runs smoothly and all the rewrites work well it’s just that the panel is not working. The login screen seems to work but once I try to login it just stays there. No error message being thrown anywhere.

The basic configuration stuff was taken from: nginx setup · GitHub

Any Nginx user that can help? This is the server configuration file:

server {
          #error_log /var/log/nginx/vhost-error_log warn;
          listen X.X.X.X:80;
          listen [::]:80;
          listen 443;

          }
          charset utf-8;

          # panel links
          location /panel {
                index index.php index.html index.htm;
                try_files $uri $uri/ /panel/index.php?$uri&$args;

          }

                return 403;
        }

}

And here’s the last two errors from the nginx_error.log

My configuration is bit different and works:

location ~ /panel { # with the ~
    index index.php;
    try_files $uri $uri/ /panel/index.php?$uri&$args;
}

Does that work for you?

[pedroborges]

Actually looking at the error message it looks like your problem is not Nginx. I had a similar issue when trying PHP 7 beta back in December. Since the stable release came out I have had no issue.

The solution will depend on your OS and PHP version. Googling the error message help me at the time.

Thanks for the suggestion!

The system admin mentioned something about rebuilding PHP tomorrow. In the meantime I’ll try to learn more about those error warnings.

So, the system administrator solved it with the help of this thread:

Cant login to Panel

Okay, I finally managed to fix my error. For future reference - if anyone stumbles upon the same mistake - follow these steps Turn on debug in your config file Localize where the error occurs (in my case, it was when I tried to access /panel) Insert following into the file, where the error occurs: session_save_path(sys_get_temp_dir()); Save and upload That did the trick for me! Thank you all for your inputs during my error-finding Best regards Aris Kuckovic

It seems Kirby was looking for the PHP session in a different route than configured.

Anyone can help? Where i should put “session_save_path(sys_get_temp_dir());”??? Thanks in advance!
