Hi,
I am getting crazy!
I tought everything is working, but now i get complains from customers that the french version is not working properly.
I have translated all categories with FaLang. when i try to open my category-page, nothing happens with the subcategories.
eg. walliser-weine.ch/shop/index.php/de/weinangebot
works fine when i click on a category
When i change the language to french for the same page
walliser-weine.ch/shop/index.php/fr/nos-vins

the subcategories do not show up or an error msg for some of them.

What could be wrong?

Many thanks for your help,

Regards

Markus

I reentered the translations. It is working now.

Thanks
