About [[MediaWiki:Mobile-frontend-profile-last-thanked/cs]]
Mobile-frontend-profile-last-thanked (stránka neexistuje) and Mobile-frontend-profile-usertalk (“Komunikovat s {{GENDER:$1|uživatelem|uživatelkou}} $1”) specify an optional GENDER-related parameter in their documentation ($3 in MediaWiki:Mobile-frontend-profile-last-thanked/qqq, $2 in MediaWiki:Mobile-frontend-profile-usertalk/qqq), however, using the parameters causes the "undefined parameter" errors to be displayed, and the messages marked as fuzzy.
