A few of my users are reporting that our Mahara installation always refuses to pass valid responses to CAPTCHA challenges in register.php. That is, while most users are able to successfully pass the CAPTCHA challenge when trying to register a new account, there are a few users who consistently fail to pass the challenge, particularly when they enter the correct strings. My website is www.c3ontario.com.
It's unrelated to browser type. I've had people using the same browser version on the same operating system version but on different machines have different results from the CAPTCHA challenge. I have confirmed that the server setup does not play any role whatsoever in this experience. Cookies are enabled. Unicode UTF-8 character sets are always used.
I cannot reproduce this error myself. I upgraded to 1.0.9 but the behaviour remains. I'm at a complete and total utter loss.
I was wondering if anybody could please describe briefly how the CAPTCHA challenge part of the software is organized. That way, I can try to trace through the code and figure out what may be going wrong. It's never easy to understand other developer's AJAX implementations.
Thank you very much for you attention. As well, thank you for developing such a spectacular system!
