I was few days offline and it looks like it was ideal situation to apply Murphys law and break thinks on my website. Bug tracker was not able to log you in or if you managed this step, you could not post anything. This issue seems to be caused by some bug in lighttpd which I'm not able to reproduce on my devel machine (most probably because of it is 32-bit and server is 64-bit).
phpMyAdmin demo server didn't work at all because somebody hardly break mysql database and my restore scripts didn't properly handle this situation.
Right now everything should be back working, please report if there are any other issues remaining.
