Captcha Service Not Responding

I'm checking the debugger and see the attached.

I've tested the connection and it passes. I've also enabled all captcha types in CB. 

It seems to only apply to:

• Clipbucket
  
• Dolphin
  
• ZENDESK
  
• NING
  

Anybody else finding CB not working on these? 

Sorry! I just checked the new threads and another thread was opened while I was posting this one!!! Crazy, I know, but it's true!

Maybe it helps knowing these platforms are generating this message. 

Here's the other thread so it can be merged and future people can see the cause!
