WPtouch plugin only shows mobile site when I'm logged in

I’ve activated the WPtouch plugin and it runs smoothly but I get the desktop-version again as soon as I log out. Regular visitors also get the desktop version. T’ve tested it on an Android phone and an iPad, both display the regular, non-mobile version. I have no clue what causes this, only when I’m logged in to the admin account of the site on my phone do I get to see the mobile version. Running WordPress 3.2.1. and WPTouch 1.9.33. Anybody got an idea? Thanks in advance.
