URGENT HELP NEEDED!Users cannot login to live site

HI,

We have recently migrated the website to another server and ever since we have been having various issues.

www.kilikanoon.com.au

Since the migration we ended up having to add an extra user group "registered", which became a parent to the Kilikanoon group ( which was just the original "Registered").
The problem is that when users sign up and are automatically added to the new "Registered", their login details do not work until we actually manually assign them to "kilikanoon" group.

What am I screwing up and where???

We cannot make any changes to Kilikanoon group as there are a lot of privileges through products, prices and variants related to it.

Thanks in advance

Solved the issue....

Sorry to bother everyone.

Turns out i have not changed user group permissions in the global configuration....
Anyway, hopefully i am not the only one that can get lost in the piles of settings and they will find this useful.
