multi language multi site problem

Considering the link on the logo it seems that the site has moved to https://isciencebox.de/language/en/home/
Also, when going to the main URL that’s where the site redirects to too, but from there it wants to redirect again, which causes a loop.
The homepage seems to be https://isciencebox.de/language/en/

Something else that is weird, the links on the flags are:
German: http://isciencebox.de/language/de
English: http://www.isciencebox.de/language/en
So, the language shouldn’t be there, but one has www and the other not.

http://www.isciencebox.de/en & http://www.isciencebox.de/de are not working, that’s a 404 page there, saying the pages do not exist.

Frankly, there seems to be more wrong than just the language.
Can you recall what exactly you did to change the it?

I think it would be best to return on your steps.
Perhaps deactivate the plugin (assuming you used one) and try to make sure that everything works correctly before you give it another try.

I hope it helps. GL!

As far as I know, polylang and qtranslate do the same, so you should use only one or the other, not both…
But I see it has improved already 🙂
Bon courage!

Here it seems to work fine. The menu changes, the content too. The language flags, however, do not show up in the German menu. There is text instead.

What I find a bit weird, though, is that all content is in a language folder. Not https://isciencebox.de/en/, but https://isciencebox.de/language/en/. It would be better to change that, since ‘language’ probably has little SEO value (at least not for all pages).
