Everywhere I read about a php.ini file… But my package only includes a php.ini.sample file.

Thats where I changed a few things without any succes. This is the original code:

; This file is for CGI/FastCGI installations.
; Try copying it to php5.ini, if it doesn’t work

; adjust memory limit

memory_limit = 64M

max_execution_time = 18000

; disable magic quotes for php request vars

magic_quotes_gpc = off

; disable automatic session start
; before autoload was initialized

flag session.auto_start = off

; enable resulting html compression

zlib.output_compression = on

; disable user agent verification to not break multiple image upload

suhosin.session.cryptua = off

; turn off compatibility with PHP4 when dealing with objects

zend.ze1_compatibility_mode = off

; PHP for some reason ignores this setting in system php.ini
; and disables mcrypt if this line is missing in local php.ini

extension=mcrypt.so

Very anoying…
