Some folk have been having difficulty with the Fun Captcha at login.
Thought some step by step instructions might help as I can see where the difficulty is.
Go to the site and put in your login details
The Fun Captcha screen appears
Do the recognition tasks
Fun Captcha tells you that you are not a bot
Do Not Click On the Login Screen Again
If you do you will be taken back to Fun Captcha and that is where the issue has been.
Remember Click on Continue but not on the Login Screen Again
See how that goes and let us know
