Links are not highlighted

Hi there,

I bought the theme package and installed Onigiri. My website, so far, is finished, with one problem: Links are supposed to be highlighted in blue – but it doesn’t work for me. I can’t see the difference between text and link, see here for example: http://khesraubehroz.com/portfolio/hier-oben-iii/ – I can only “see” the hyperlink when I hover the respective word but only because it is underlined then.

Thanks for your help!
