Plone 3.0 users and groups: show all

Question

I have a problem that when I enter users and groups page and I press show all, it will show nothing or just a few members within one page instead of showing 20 members in a page like before, why is that?

Recently I have set plone captcha to prevent robot registration, is this setting has anything to do with my problem?

Answer 1

Is an old problem of Plone 3 user and group handling. If you look at the site log when accessing the view you'll probably see something like "Skipped user without principal object ...".

It mean that the portal_memberdata tool contains some old user data that are not referring to real users: probably you changed something in the user and groups management, like removing a source of users.

Unluckily Plone 3 do not offer a way to fix this in a simple way. On Plone 4 the portal_memberdata from ZMI offer a way to cleanup things.

This is not blocking your site from working normally and is not a critical problem (although I understand is annoying)
