I try to login using stack exchange account in Opera. When I click "Submit" button, the placeholder where the login fields were get replaced with:
Not Found This page could not be found.
The outer contents, headers and footers, remain same.
- Log in with Stack Exchange
- Enter login details and submit
- "Not Found" http://stackoverflow.com/users/login#log-in
Win XP, Opera 11.10, default settings, cookies enabled, no addons, reproduced on 2 machines.
One system still has this issue. I disabled anti-virus and firewall, tried to login in a private tab (to simulate clean start) and the issue occurred again.
I used Opera's "Inspect" option and found that the login form is displayed in an IFRAME, with source being
https://openid.stackexchange.com/affiliate/form?.... If I open this URL in a separate window, I can login just fine and get redirected back to where I came from, but if I want to use the normal "Log In" page the "Not Found" problem occurs.
