Site does not display in mobile version

Hi,

I installed mobile joomla on my joomla 2.5 site. It had worked fine on joomla 1.5, but I can't seem to get it working on 2.5. I have mysqli installed (or so I believe) and everything is active.

Site not working: www.retraitecentrum.nl/j25/

My main site is working (running on joomla 1.5).

Help??

Seems to work fine on iPhone.

It doesn't show on iphonetester.com or sites similor. So maybe it does work for iPhone?

It sure doesn't work on my Android device...??

iphonetester.com is not an emulator, it just displays desktop version in iframe.
