The problem was that the registrationinfo.tpl template was overridden and did not contain the users node_id in the activation link. In eZ 3.8 this was not necessary while it is now. So the activation link was wrong for eZ 4.2. I could solve it by chainging
{'Click the following URL to confirm your account'|i18n('design/standard/user/register')} http://{$hostname}{concat("user/activate/", $hash)|ezurl(no)}
to
{'Click the following URL to confirm your account'|i18n('design/standard/user/register')} http://{$hostname}{concat("user/activate/", $hash, "/", $user.contentobject.main_node_id)|ezurl(no)}
So people upgrading from old eZ version to 4.2 an have their own registration template, might need this as well.
Glad to see you were able to find the cause of your problem and were able to fix it. These feedback posts are valuable to other community members e.g. eZ users.
Could you please edit the original post, and add [SOLVED] in front of the Subject?
