Call me a newbie, but check out this warning from the forum. I've gotten it twice in the last 2 days. I've been using the forum for the last 2 months, and I've never seen it. And before you ask "have you forgotten your password", no, I haven't, and I've never gotten a "bad username/password combo, please try again" type of message - I log in perfectly each time. Except now I am getting this (screen shot attached).
This fix seems to be to click "I forgot my password", and let it reset your password. However, I get this error 24hrs later, and regardless of how I enter the Captcha, I can't get in until I give it a "I forgot my password".
Anyone else getting this?
