I have used the "Resend Confirmation" Command in the CB User Manager.
The url generated to activite the user has following format:
www.p-m-a.at/index.php?option=com_comprofiler&task=confirm&confirmcode=reg4de7215a63fbe23c14a84fec9f7c2d500326eb51&Itemid=100
including the ItemID of the CB Profile.
During registration the ItemID is not added to the link - and this is correct from my point of view.
In real the Menu to the CB Profile is restricted to registered users. So nobody is able to confirm because joomla will redirect based on not logged in, if you use the "Resend confirmation" function of cb.
Please remove the ItemID in the link.
