Yusuf Patel 1988 on "403 Forbidden nginx"

Hi there,

I'm using Indie Fest theme and recently I got an error above my header, saying:

403 Forbidden nginx

The site is displaying fine, just this little eror message.
I checked on my permissions for the header file (and related) but no success...

Anyone who had a similar problem and knows how to solve it?

Would be highly appreciated!

here is my site: NS Designs

thanks a lot!
