Having had the captcha pop up when posting, I've so far failed to persuade it that I'm human.
This is not a gripe about the difficulty of it, the frequency of popups, etc. it's the technical fact that EVERY time I submit the answer the ONLY response I get is:
"An error occurred submitting the CAPTCHA"
I have disabled EVERY security/privacy/adblock plugin in Firefox:
- Adblock Plus
- HTTPS Everywhere
- Firefox's inbuilt Mixed Content Blocking (XSS protection)
The Firebug console shows nothing error-wise, I've got no other plugins running, and the Captcha window gives no other feedback.
