I feel stupid for not noticing this until now...it worked fine back when we were using the Fashion theme, but then we switched to Alfresco. We are now running 3.10 with the 3.10 Alfresco responsive theme.
I've got Captcha enabled in my general settings >> security, however, the captcha is not appearing on any of the forms that I have it enabled for??? Oh...and when a new customer tries to register, it says the text didn't match the picture...as if it IS being displayed..
What might cause this problem?
