I have just tried to log in JIRA and this is what i get even when i enter the CAPTCHA: Sorry, your userid is required to answer a CAPTCHA question correctly.
Your captcha had a count of 606 failed attempts.
I don’t even understand how’s possible, unless you have a dashboard or something automatic with your username.
Let me know if that didn’t fix your problem.
Strange indeed. Now it works and thanks! 
The issue has surface to me : Sorry, your userid is required to answer a CAPTCHA question correctly.
Since morning have been trying to login Wiki and Jira but I could not, just throws me error message: Sorry, your username and/or password are incorrect. Please try again.
