Hi,
I have Joomla 3.9 with 2 languages and SEO friendly urls.
On an article page, (not in the list of articles) the filter disappears when the alias (=URL) is translated. Strangely enough, it does not matter if the category name is translated.
Example:
original:
domainname.com/index.php/en/all-houses/25-article-description
change of language tag and category name translated
domainname.com/index.php/de/alle-haueser/25-article-description
Filter is there.
article alias translated
domainname.com/index.php/de/alle-haueser/25-article-beschreibung
the filter disappears.
Have you got any idea where I should search for the problem.
