hi again,
latest version of 1.6.x is not 1.6.3, but 1.6.6. and it works fine for me there.
i now tested 1.7 as well and i am also getting an error.
500 - An error has occurred.
View not found [name, type, prefix]: profiles, html, adminView
it somehow goes to this page:
http://xxx/administrator/index.php?option=com_admin&view=profiles
when i switch to the bluestork template it works fine, the link is:
http://xxx/administrator/index.php?option=com_admin&view=profile&layout=edit&id=42
in j1.6.6 where it is working fine for me it opens:
http://xxx/administrator/index.php?option=com_admin&view=profile&layout=edit
i will ask the developers to take a closer look, thanks for reporting.
