my captcha timer is increased,why?pls need help
What does it say exactly? Also, what timezone are you in?
my time zone is GMT+6. i start with 16 second..now it increased to 48 second!!

Your computer clock time is drifting. I set my timezone to GMT+6 and I had a 6-second timer. Then I set my clock backwards 30-seconds, and now I have a 36-second timer. This means that your computer time is somehow incorrect. If you set it ahead 6-7 seconds, subsequent form submissions won't go through. If it gets set backwards, you will have a problem like you are experiencing. There's nothing we can do to fix that problem you're having, unfortunately.
Are you on Mac or PC? Make sure you have time set automatically.
i am using desktop pc with system windows 8.1 . ill try to follow your instruction tomorrow,now its 2 am in my country,i need to sleep..good night and thanx for giving me the way to solve my problem
I was explaining my tests but I don't have a solution. I do know the problem is with your computer not keeping accurate time.
Edit*** I just tested on a computer with Windows 8.1 and the timer is off too. I'll try to find a solution but I'm not positive I will. It does seem Windows-related. Possibly Windows 8.1-related.
For now, you can refresh the page after each success. Or, try to set your clock back 42 seconds.
