community builder and k2 do not integrate users

Hi I am using latest version of CB with latest 2.5 joomla and k2. I am using CB login module and it worked fine until today, now visitors cannot register on my site anymore.
Any suggestions would be greatly appreciated
Thanks

Its ok I solved it anyone else with this problem should
try this

Check that K2/advanced / Enable reCaptcha on registration form is set to 'No'.

Sorry... I realize this is an older topic, but I thought other users would find the answer to my question more easily here than in a separate topic.

I'm using K2 2.5.7, CB 1.81 and GroupJive. I've got the K2-CB integration enabled. Should I use the CB Login/Registration modules? Is it possible to use the K2 categories for GroupJive, or I need to duplicate my categories to use K2 and GroupJive?

Yes, you need to use CB Login module.

You cannot use K2 categories in GroupJive.

I cannot find the path to enable this. please help

I am also using CB and K2 for a website and I am interested in combining the two. Your answers here is puzzling. Where can I set permissions for my K2? I am using joomla 2.5.4 and don't see it anywhere. Any help would be greatly appreciated.
