Problem with joomfish country code in url

Hi

I'm using sef advance with joomfish, german (de) and english (en),
and once in a while I'm experiencing the following problem

urls with the following code
www.justasite.de/ de/news/machine-news.html

are switched to
www.justasite.de/ delete/news/machine-news.html.

The de for germany is replaced by delete, and a 401 is shown,
which is not good when a google bot crawls my site.

Please tell me what the cause might be and how to avoid this.

Any help is appreciated.

You can't replace "de" with "delete"!
The language code must be 2 characters long, otherwise SEF Advance will not recognize it as language code.

I don't want to replace it with delete.

SEF Advance replaces de with delete.

And this is my problem.

The weird thing is that this problem occurrs once in a while.
I have no explanation to it.

Maybe you have.

Check your Joomfish settings, that language tag is defined as "de". Don't know why it would replace it...

my joomfish settigs are o.k.

I have no clue why this happens.

I have two languages, en and de. And it occurs only with de.

It's not SEF Advance that does it. Possibly it's some other component that conflicts, never heard of that.
