I'm having some problems with Tank Auth. Although i followed the instructions from here when i try to connect in the login_form i get a redirect in http://example.com/auth/login.
I assume i can change "example.com" with my domain but i can't find where. The other thing is that captcha is not showing.
I suppose i have to learn only from the examples coming with the installation?
Any help is appreciated.
Here are some (more detailed) instructions on getting Tank Auth to work in CodeIgniter: http://expertnotfound.wordpress.com/2011/01/20/setting-up-tank-auth-2/
(Sadly it does not seem to be 100% compatible with CI 2.1.0. But it still made a difference for me...)
