Wikimedia Bugzilla is closed!

I upgraded to version 1.5.5 of media wiki
I successfully ran php upgrade1_5.php
I successfully ran php update.php

As I went through the pages to check out and make sure all is well I received this display;

Tag conditions not met. This should never happen and is a bug.
