reCAPTCHA issues on some version of IE 9.
Hello,
I have created a force.com site and I have published it. During my internal testing I found that everything worked flawlessly. I tested the apex forms system with captcha on Chrome, Safari, Firefox and the latest versions of IE7 to IE10. Not a single glitch.
However as soon as I published the site, my call volume went from 30 calls a day to about 75 calls a day. The main problem, is that the captcha is not submitted the forms field for version of Internet explorer 8 to 9 that are not running the latest version. Since so many web visitors are not running the latest version, they call and complain. This was not an issue before I started using force.com sites.
I have copied the steps at http://wiki.developerforce.com/page/Adding_CAPTCHA_to_Force.com_Sites.
Line 24 and line 29 always return null on IE 9.0.8112.16421. Therefore visitors cannot submit the captcha with success.
So basically I can only test changes by publishing it on my site, then wait a couple of days and see if anyone reports an issue, or not.
I have set standardStylesheet="false" on the forms. I think that could be it but I will need a few more days of customer feedback to be sure.
Interesting. So it looks like perhaps an apex form issue in these IE versions rather than a reCAPTCHA issue. I tried with IE 7 - unfortunately it was on the latest version of 7. So couldn't recreate it.
Yes, but here is the interesting thing. When I use the same code in a java or php program, I do not get this captcha problem. It seems the visualforce css or javascript interferes with the captcha code in older versions of IE.
