For those who just got themselves a brand new server with CPanel, in my case with CentOS 5.0 OS.
The easyapache compilation does not put:
; Whether to allow the treatment of URLs (like http:// or ftp://) as files.
allow_url_fopen = On
allow_url_include = On
inside php.ini, it is a security matter for sure but those ppl who still got includes like url inside their customers scripts, edit /usr/local/lib/php.ini and add the line above
Hope this helps someone
