Don't get twig for hhvm, how to find the problem?

Question

Twig

After connecting Twig in the project, it says "Server error 500", ini_set('display_errors', 1) and error_reporting(E_ALL) do not help, I don't see what exactly is wrong and I don't understand where to dig, please tell me.
under normal ngnix + php-frm 5.6 everything works fine.

Answer 1

the problem was that I rendered the template in the destructor of the controller, the destruct in php is called automatically after the entire script is processed, in hhvm the destructor had to be called explicitly after the controller was completed.

Answer 2

and what's in the logs hhvm?
well, we must remember that ххвм is not a complete implementation of php
