Hopefully easy question?

[eluser]NICJerry[/eluser]
I am not a CodeIgniter user myself and I have a very simple working knowledge of PHP. My problem is a new client just dumped an existing website on me that was apparently written with CI. They have an admin section which they must log into but now they want to do away with the captcha routine.

As best as I can tell, this site was written with CI 1.0 and is using DX_Auth for authentication. So the hopefully easy question is:

How do I disable captcha?

They want all the same functionality, just without the captcha routine getting in the way.

If more info would help, please let me know what I can dig up. Thanks!
