Qtranslate is not compatible

Hello,

When I activate Qtranslate, I do not see my page content. I see the theme header, the title of the current page and after this, the container ‘stop’ and I do not see anything else.

I use all recent version :

Wordpress 4.01
Qtranslate 2.5.39
Catch Kathmandu Pro 3.2

I need your help !!
