Save change in super User

I have problem while save change in super user. Have this message:


Error

Save failed with the following error: You cannot remove your own Super User permissions.

Well its clear you changed some permissions and you can not do that for own super user account. Maybe you can change that using other account that belongs to super-user group

I am not changed permission, I am only installed hot hothotel31 hot start and upgrade joomla 3.2. This is the first time that we are something happening.

What are you changing then?

When you get into super user and I just want press save appears to me that the error.

I will try to re-install Hotstart, so I'll see if the same errors

.......

I am install again hotel hotstart from hot_hotel31_hotstart.zip and first after instalation I am go in to Super User from user manager. I am not change anything just press save or save&close and I have this message:

Error

Save failed with the following error: You cannot remove your own Super Admin permissions.

open you db directly using tool like phpMyAdmin, open table #__assets, find record with title field equal to 'Root Asset', change filed lft to 0
