Some forum thread do not load properly

I have been trying to find answers to certain questions and I find that the pages do not load. They seem to go into a reload/ refresh loop, but there is no data where you would expect the forum information.

Hi,

It is because the thread was set to Private mode. 

This is done when the original topic/thread owner requires confidentiality in the discussion thread.

Like the thread http://www.jotform.com/answers/453441 you mentioned.

Thanks.
