Can't Change a User's Group - Joomla! Forum - community, help and support

-

i'm trying give moderators (from forum) moderating abilities in joomla+cb website. decide, in cb, publishers group moderators....

the problem is, when go com_users , try change specific user "publisher" group, popup button comes saying
"this email registered. if forgot password, click lost password button , new password sent you."
wtf? acting if i'm trying register user, email in use. normal? not changing user's group correctly? if so, go (in backen) make user publisher?

go user manager cb change user's access level. make sure autocomplete in browser isn't filling in blank fields causing duplicate issue.
