UberSVN cannot access the administrator dashboard

I've installed UberSVN (I think it's 12.11) on a mac mini (OSX 10.8.2) - this is a fresh installation installed a few days ago. I've been using tortoise SVN to access it from the a PC. Everything seems to be up and running, can check in and check out fine.

But when trying to access the console and logging in successfully I get the following error.

type Exception report

message
