Time has passed, and it has come time to update to the latest version of Bugzilla again. Sadly not everything managed to come along for the ride this time though. Our custom theme has been bitten by a series of incompatibilities with the newer version of Bugzilla which has prevented people from changing their email address and entering bugs in some cases among others things. As it is more important the site is usable we've had to disable it.
We are interested however in getting it fixed - those who have knowledge of HTML/CSS can help in particular. More details can be found in this kde-community post: http://mail.kde.org/pipermail/kde-community/2014q3/000860.html
