ioncube loader error what is the problem?

Question

PHP

Help solve the problem. When running the script, nginx gives the following error:

2016/10/02 16:45:55 [error] 17035#17035: *2240 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Decoding error - Unable to call protected script body in /home/www-data/site/site.ru/index.php at line 0.
 in Unknown on line 0" while reading response header from upstream, client: 105.82.252.89, server: site.ru, request: "POST /admin HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm/www.sock:", host: "site.ru", referrer: "http://site.ru/admin"

The script is protected by an ioncube.
Razarb throws up his hands and says that this is a server jamb.
Throw at least some guesses. I tried all the weights of the ioncube.
system: Centos 6.7 nginx+php-fpm
PHP Version 5.6.27RC1

Answer 1

Problem solved.
The script transplanted to another unix socket, the errors disappeared.
Another script of the same author worked on the same socket, it seemed that some kind of conflict arose.
