Transfer site to nginx + php-fpm + eaccelerator

Question

PHP

Good morning everyone.
There was a need to transfer the site from apache to nginx + php-fpm + eaccelerator because the server could not cope with the load. Site on CMS Bitrix.
At the moment I have a server where I installed nginx + php-fpm + eaccelerator. Installed and configured everything, restored the backup copy.
But, when you open the site, it swears:

Fatal error: Cannot use string offset as an array in

Answer 1

try the script
www.1c-bitrix.ru/download/scripts/bitrix_server_te...
run through a browser on your website

Answer 2

And what is written after "in" ? Look there.
In addition, you can google and run the bitrixtest.php script, it will show which settings and extensions necessary for proper operation are missing.
It looks like you don't have ZendDecoder in PHP, or even an old version.
