Empty $_REQUEST

Hi, I have a apache2/php app written for php version 4 and have moved it to a system running php version 5: Old: PHP 4.3.10 New: PHP 5.2.6 with Suhosin-Patch 0.9.6.2 When I run the app I find that $_REQUEST is almost empty. it contains PHPSESSID but none of the data submitted through an html form. /etc/php5/apache2/php.ini has both: variables_order = "GPCS" request_order = "GPCS" (I added the 2nd line just to be sure.) Is there something else that needs to be turned on to get form data into $_REQUEST? An dd thing: If I issue phpinfo() before print_r($_REQUEST); then $_REQUEST does contain all my form data!
