Here you go:
1.
Menus on the left look normal (Beez2 on Joomla 2.5.
with indenting, highlighting.
2. Clicked on 'HikaShop - User Control Panel' menu
3.
HikaShop asks me to log in (I wasn't logged in) but left hand menus seem to have lost formatting (indent, highlight)
4. CLicked on 'Don't have an account?' link
5.
Shows HikaShop registration (because of enabled redirect plugin) but menus still have lost formatting.
Does this help you diagnose the problem? Is it something to do with these pages not being associated with a Joomla menu?

Martin
