By default remote code inclusion is not allowed in Php 5.2. This is an important security improvement over the previous versions.

However, some scripts may require to include remote code in order to work properly. For this purpose create a php.ini file and specify the following line:

allow_url_include=on

This will change the default Php directive and allow you to include remote code in your scripts. Copy this php.ini file in each directory you'd like to have the setting applied.
