Nginx 500 internal server eror after update


just wanted to update my IP-installation from 1.5.2 to 1.5.4.

the old installation was working perfectly, but after copying the new files to the webspace and calling, I get an 500 internal server error.

running nginx on debian with php7.0

after having a look at the error.log I assume, that something’s not correct with the vhost entry:

2017/10/23 18:27:31 [error] 13240#13240: *25 rewrite or internal redirection cycle while redirect to named location “@php”, client:, server:, request: “GET /index.php/setup HTTP/1.1”, upstream: “fastcgi://unix:/run/php/php7.0-fpm/web10.sock”, host: “
