After upgrade (3.1.0-1 to 3.1.2) the main language (English) is fine, but the secondary language (German) shows »navigation.archives«, »navigation.about«, etc.
Reading Menu problem in OJS 3.1 (bug?) and NavigationMenu Feature - Locales for default NMIs retrieved from key and not database · Issue #3846 · pkp/pkp-lib · GitHub I thought, the problem was solved.
Any ideas, why this still happens?
