Hello!
I am developing a site on Yii version below 2. There are 2 working servers: one is on xampp (php 5.3) Windows, the other is remote on Ubuntu 14.04 (apache + php5.5)
The problem is that everything works fine on Windows, while Ubuntu displays this such a mistake

Class 'CListIterator' not found in <b>/var/www/myproject/yii/framework/collections/CList.php</b> on line <b>90

ALTHOUGH in fact , CListIterator.php is right next to it
Probably a problem in the php settings?
Bues over 3 hours on this issue.
Thanks
