I had a problem with the free responsive theme where the content text doesn't show in Chrome. The text is there, you can select it and it is visible in the source code but it just doesn't appear. Images are visible, only the text is missing.
From this thread I found it is a bug in FitVids.js version 1.0: https://wordpress.org/support/topic/wp-doesnt-display-content-text-on-chrome. The bug is solved in FitVids version 1.1 which is available here: https://github.com/davatron5000/FitVids.js/blob/master/jquery.fitvids.js
Until the developers of this theme updates the version of FitVids you will have to replace it yourself.
