sef and ezrealty

I have a strange message when I have more then one page. I tried several things but could not find the right solution.
Maybe someone knows how to fix it.
First page url www.mandi.be/en/ezrealty/viewcategory/1.html
This is correct when I go further want to go to the next page, this url is what I came to is.
www.mandi.be/ezrealty/viewcategory/en/ez.../viewcategory/1.html
Then I got the message: You are not authorised to view this resource.
You need to log in.
Down in the screen firefox was the url displayed before activating it
url www.mandi.be/ezrealty/viewcategory/1.html#next without en for english

when I type manualy www.mandi.be/en/ezrealty/viewcategory/2.html
it is coming to the right page
What can I do about it?
