Urban Giraffe Support

I'm sorry to be the first to post here, but I have had problems installing this theme. I'm trying to install it locally on a test set up and I get this error message in preview :

Fatal error: Call to undefined function automatic_feed_links() in K:xampphtdocswp_testsitewp-contentthemesguangzhoufunctions.php on line 28

not only is it impossible to install the theme, but for some reason it persists. When I try to quit the themes page I get the same message and a white screen.

It may be something to do with plugins I have installed, but I have no idea what to look for.

It's a pity because it seems a very interesting theme
