I've installed skeleton app via composer and when pointing the browser to the public folder with virtual host I get the error:

What can I do? I use Php 5.6 in Plesk panel (Centos 6.6)
Your PHP version and Zend Framework version are incomatible. I've learned that PHP 5.3.3 only supports Zend Framework up to version 2.2, this is not meantioned (clearly) in the Zend Framework documentation.
