https://www.mediawiki.org/w/index.php?title=Special:Log&page=Category%3AAbortLogin+extensions%2Fru not sure what you mean with 'empty category' but there is actual translation. And original (english) page requested for translation. Maybe this page will be 'full' with other translation later, dunno.
Topic on User talk:Shirayuki
Do not create empty categories.
Then translate it as you want.
To me it looks like you doing some sort of vandalism
@Shirayuki Please do not delete translations. The parent category exists, and if the category is empty this is because there's no Russian translation yet for articles in that category, but those translations may be created in the future and the category will be required
I see, but the category is empty for many years and source pages are not prepared for translation.
maybe then problem in translate marking on original page. on other wiki we don't add categories part of page at all in translation, but then only english categories linking available
