Language parameter in URL

Hi,

when switching the language in one of our shops (EE 4.1.2) we get following result:

German: http://youraverageshopurl.de/home/
English: http://youraverageshopurl.de/home/3596227959/

I just don’t find, where or why this happens. :confused: Any hints?

Bye,
Terrance

Q1. have you changed SEO urls allready ? -> can be a result caused by manual configured SEO URLs …
Q2. check the language settings in the first chapter of basic settings… might be there is some problem going on.
