I see your problem, The PHP pack you are using right now doesn't allow /e modified with preg_replace
You might need PHP pack V3
This version of PHP is much more relaxed in regards to security. More features are enabled compared to the default version.
* Mail(), eval() functions allowed
* Memory limit and max upload filesize set moderately higher
* URL fopen or include enabled
* More relaxed restriction of 'unsafe' and 'bad' functions
* PHP Version - 5.2.4
* cURL, FTP, Socket, and MBString extensions enabled
* /e modifier with preg_replace allowed
* No system/execution-related functions enabled, eg: exec, passthru, system
* Magic Quotes GPC enabled
* Register Globals disabled
* File uploads enabled
* Suhosin Path + Extension installed
