After copying the codeigniter, new site is using old view paths?!

Hi guys,

I will try to explain the problem I am having problems with.
I have a website, lets say; website.nl
The whole site is in Dutch. We bought a new domain; website.de.
I created a new account on our server, and copied the whole website-directory to the .de directory.
When I translate my views, and I visit the .de website, the views are good on the homepage. Yet, when I try to visit another controller, it shows the views of the .nl website and not the .de website. I checked if the domain .de is, and it is.

How is this possible?
