Community Auth system - unable to login using test

[eluser]Unknown[/eluser]
Hi there,

I'm a bit of php n00b, so apologies if this is really simple. I have installed the full version of Community Auth but am unable to login as a test user, despite using the passwords in the database. I have tried all the debugging advice (http://community-auth.com/documentation/login_debugging) but nothing has worked. Has anyone experienced this?

Thanks
