I am having trouble with my child theme. You can see it here: http://184.108.40.206/
I used your child theme. Installed it as you said but for some reason the header is just not working. The logo doesn’t show up. It loses transparency, doesn’t turn black when scrolled down, and generally doesn’t look the same.
The video in the center of the page is also out of whack.
Other than that, I really like Airi. It’s a nice design.
