Hallo allerseits,

wieso bekomme ich mit PHP5.1
diese Fehlermeldung

Fatal error: Call to undefined function mcrypt_module_open() in E:\www\lan.domain.tld\versuch2\cookie.php on line 23

Also ich habe es jetzt doch selbst gefunden. Es gibt eine Extension in der php.ini

extension=php_mcrypt.dll

welche disabled war.
