Hi Nick,
Thanks for your prompt reply. I now recall having the same problem with cb_list a while back where it took a while to find the answer because it is not "obviously" (to me) located or searchable online.
I'll add it here for future reference....
Question:
How to get the cb_list module working?
Answer:
Add a new user menu item as a Link-URL and point it to
index.php?option=com_comprofiler&task=usersList
(this will be the searchable users list).
Cheers.
