I just checked, and I could view my orders again. But there still is something wrong, because when I pressed on the com_joomsef3 I saw got redirected to the frontpage of the e-shop. I just copied the id from the URL generated, but when I saved the config it did not give me any confirmation that it was working or accepted, this should be addressed.
Also, the password field is clear text and not a password field. I do not like that, I prefer all my passwords to be starred, even if it is in the backend. I also have noticed that the new menu for the component creates some blank entries (under "Upgrade" there is an empty space that links to the dashboard, same under "Manage 301 redirects"), in Firefox 3.0.14 (Linux version). But other than that, I like the new config screen, but I would prefer if you used less sub menu entries.
