O my end everything is good. Please be more specific about the problems you are experiencing.
When I go to look at the showcase sites on your website, sites that use your theme the image viewer is completely black. The thumbnail does not expand to the larger view. I am using firefox on windows 8 and also it does not work on my mac with chrome or firefox.
You’re right, I just found that it is an issue with the plugin I was using, I disabled plugin, you can open images directly now.

I was unaware of this problem, because I use latest Firefox on W8.1 and somehow it works, but IE11 and iOS Safari fails.
Thanks for letting me know!
I found that CSS3 Lightbox plugin created this conflict. So WP 3.9.2 and everything looks fine! Gallery should work now 🙂
ok great I will check it out. I really wanted to see the sites 🙂
Thank you!
