Cloudfair blocks login requests from opera browsers if trying to login through the main POE site.

it gives you a error saying your browser is out of date. I was able to get around it by using my login at the Filterblade site that redirected me back to the POE Authenticate page. I can logout of POE site and then im back to square one again where it wont let me login because cloudfair thinks its responsibility is to make sure your version of browser is up-to-date.

I don't know if GGG staff can do anything about this even because it is a problem with cloufair and the way they handle there services. That bieng said if anyone else is having this problem then just use filterblade to login to the POE website.

Just a guess based on what an other player had said they were doing.

Opera may be getting blocked because it can effectively cause DDoS like effects because of it's low system impact (your own PC) i know at least one person that had hundreds of tabs open live updating the trade page, while you can do the same sort of thing on chrome or firefox their impact on your PC is enough that you wouldn't get enough tabs open to be a big problem.
