Login bugged

I have no problem surfing the website with my trusty broswer Opera. I had no issue surfing and logging before with Opera as well. I don't know if it's since the new skin and all, but now I can't log in with Opera. I'm using Firefox now because, well, it was my only way to come here and post about it. You better check it out so Opera users can log in too. And no, I'm now switching.
