What to do if Captcha is not working?
In order to separate legitimate entries from those made by bots or scripts, webmaster are using Captcha to type funny looking letters or numbers on entry forms. The Captcha are now being harder and harder to read since the computers have become more adept at deciphering captchas. So sometimes you should have trouble entering a captcha properly, but don’t be frustrating as there are some tips you can follow.
Load captcha once or more times if you do not enter the letters successfully
Sometimes people need to fill out the entry form before the time elapse among several pages, for example they need open some sweepstakes sites at the same time and work on one after another.
When the lasting time passed the Captcha will expire at the same time. Then the captcha you are seeing will not be accepted and you have to reload the page to get a new one. And when you enter the captcha before the time passed the code will be accepted.
Number 1, Lamas, and Iguanas
Because of the font the captcha uses, a lower-case "l" as in "lama" can look exactly the same as an uppercase "I" as in Iguana or the number "1." The captcha could block your entry with the confusion between these three characters.
Letter O and number zero
The difference between an uppercase letter "O" as in "Ocean" and the numeral "0" or zero is also hard to identify.
