I am running CB 1.2 RC3 and it was working fine for me. However when I installed the captcha and autowelcome, I tested the registration and it yielded a blank page after clicking the register button. I unistalled the captcha and autowelcome and registration works again. What is happening? Help anyone?

(note: I mistakenly installed the previous version of the captcha before installing the newer one... does it have an effect?)

Nevermind... got it solved already. I just removed the autowelcome.
