Proxyrama

whilst surfing this board with proxyrama this happened

http://www.chinkii.com/uploads/album/misc/phperror.jpg

it kept popping up, i actually saved it to my harddrive out of curiousity, it was a small file. Anyway i had 2 anonymous proxies chained, other sites worked ok but the divx site was green so i had to disable http1.1 in internet options>advanced , then the divx site was normal color but this site kept popping that box up. what's goin on?

Edit: oh and how come i can't upload to chinkii with it on?
