Hi,
I am using various extensions on my custom Mediawiki, like MLEB and MsCatSelect.
I have an already translated page, with existing categories, previously added : they display correctly on the translated page.
But when I go on my source page, then add categories, I can't edit them on the Translate module, and they are not updated in the translation either.
Here are my versions :
MediaWiki 1.27.0
PHP 5.5.37 (cgi-fcgi)
MySQL 5.1.73-community
ICU 51.2
MsCatSelect 6.1
MLEB 2016.04
