Where can I found the FPDF Hack for Mambo 4.5

It is no longer available

The FPDF hack that you may have read baout in the mambo server forums was discontinued a long time ago when Mambo 4.5.2 was released.

If you are still running Mambo 4.5.1 then you should upgrade immediatly as there are some well known security holes in that version
