Hi all,
I have followed instructions on the http://wikkawiki.org/FpdfIntegration to
add a pdf handler. The instructions are somewhat old. But I have gotten the
pdf handler file to work as long as there is no templates/header.php file.
How can I disable the header.php so my handler script works? Here is my
script.
