Dear Kasia,
Thank you for the answer, however, I am not sure we are on the same line.
First of all I cannot find the the widget display as per your picture.
Secondly…
Yes, I do need different widget look for different languages, in this case in the footer. As I wrote down I succeeded for categories and pages, however, I could not make it for author pages.
I do in the panel for widget (describing position of the sidebar) assigning in case of, for example, categories specific archieves categories for each sidebar in different languages (actually choosing the categories by names).
I supposed it should have been done the same way for authors archives (which are shown in archieves – authors), but it did not work the same way.
Then please advise.
I hope I am clear on the issue?
