Hello.
We use boilerplate category creation command for each new page
[[Category:YourCategory{{#translate}}]]
(I believe ir correct, if not check Mediawiki:Edittools)
Instead of automatic creation or setup Category to YourCategory/ru or /en or/lang-code
The article created as
Page-Title/ru or /en or /lang-code-subpage
As maybe connected problem, there are no categories in drop-down picker list at new page creation on bottom of editor page.
Please fix it. Thank you in advance.
