I upgraded my Opera to the newer 12.10 this morning. The site was working fine for a bit, and now when I try to access it, I just get a white page, the tab has the loading circle...it just never loads. It's working ok in FF, but I really like to use Opera.
Have you tried clearing your cache and browsing cookies in Opera? When I updated Firefox I had the same results and clearing them and then restarting helped. :)
I cleared the cache about 80 times, but never the cookies, as Opera never lets me delete cookies all at once. I deleted them by hand, and restarted a few times and it seems to be working now. That seemed to do the trick :) Sorry for posting I really thought it was the site and the new Opera not getting along. You can lock!
