Add Question - Human Verification Manager Issue

[talhatc]

Hi All,

We've recently experienced a bunch of spam bots registering on our site and making posts, we wanted to enable the Question & Answer on the registration page but it seems that VB won't let us change from the "Image Verification Options".

We selected "Question & Answer Verification" and clicked the "Save" button but still we see the "Image Verification Options". This issue persists even if we select "Disabled", "reCAPTCHA™".

No matter whatever we select, "Image verification Options" stays where it is.

We are using Memcache. Could this be related to that?

VB 5.2.2

We've tried almost everything. Nothing works.
