Hi, I am using theme News Magazine, here is my website http://toantinhoc.ga/ho-tro-lyx/
I have a problem with this theme + bbpress. For example, in this topic http://toantinhoc.ga/forums/topic/bo-sung-dinh-ly-bo-de-vi-du/ the first post is always visible, but from the second reply, they are hidden or visible when I move cursor. Anyone have idea to solve this?.

The problem does not occur when I change another theme.
