[SOLVED] Login problem

I cannot login using Firefox (Windows XP SP3). I'm posting this message using Opera.

I ask to login and enter my username and password. After a couple of seconds I'm returned to the login page. No error message is displayed and the username / password fields are blank.

I've tried running in Safe Mode but it doesn't help. I've reset all my user preferences but that hasn't worked either.

Can anyone suggest a way of finding out what's going on?

Check your cookie settings, that can help.

Cheers,

Thanks for that. Checked the cookies and arduino.cc was marked as blocked. Now sorted, able to post from Firefox.
