Link problem homepage

Hi,

If I clicking on the categories on homepage have any problem :-(

the link looks :

de/animal/dogs-puppies.html

after cklicking in browser:

de/de/animal/dogs-puppies.html

and give a error :-(

I don't know now what is the problem, then is not in all categories one have not!

cheers Sripai

So, I fixed the Problem alone :D

Also if any people have same can look here:
administration > Listing Types > ( LISTING TYPE )
go to position > Enable .html at the end of URLs > turn on " no "

Good Luck Sripai
