PHP Fatal error

[testos]

I have installed zabbix 1.3.5. When point my browser to ZABBIX URL obtain a blank page and apache this errors: PHP Fatal error: Class 'CButtonQMessage' not found in /var/www/html/zabbix/include/classes/cbutton.inc.php on line 74

If /var/www/html/zabbix/include/classes/cbutton.inc.php include in line 81 class CbuttonQMessage definition, where is the problem?

1.3.5 or 1.1.7 PHP Fatal error

In version 1.1.7 I have the same problem exactly

Fixed editing cbutton.inc.php and moving class CButtonDelete at bottom.

how it is that nobody has had this problem before?
