bbPress Topic contents not displayed with the plugin WPTouch Pro 3 on the phone

bbPress version: 2.5.2
WPtouch version: 3.1.5 (all of its official themes available see the same situation below)
WordPress version: 3.8

bbPress topic contents are not displayed on the mobile phone with only topic title seen on the topic detail page.

So is in all of the older versions of them above.

I have turned to bbPress support, but bbPress team told me to look for help from WPtouch. (http://bbpress.org/forums/topic/bbpress-topic-contents-not-displayed-with-the-plugin-wptouch-pro-3-on-the-phone/#post-141297)

Could you help me out?
Thanks.

Tom
