Page not displayed

Hello,
I use the WPTouch 4.3 and it is very usefull. BUT:
Some pages, and I don′t know why, will empty in mobile view.
Example:
https://www.equaliz.at/fragebogen/ (with shortcut to an php quizz)
https://www.equaliz.at/lebenswelten/ally/ (normal single page)

How can I debug this issue ?
