</div>My table of contents seems to have a weird problem. Whenever I am logged in to my English wiki, it displays correctly as "content". As soon as I am logged out, it displays as "Inhaltsverzeichnis" which is German. It seems to get that info from my browser.
Languages are saved in my wiki/languages/i18n/ files.
Has anyone got a clue why this is happening?
IIRC, the most common cause is that the system message containing the translation of the TOC title is cached in the wrong language. Ensure you configured the caches correctly: https://www.mediawiki.org/wiki/Manual:Cache
To find out where the problem lies, use eval.php to query with \Cdb\Reader::open and MessageCache, as in https://phabricator.wikimedia.org/T131981#2186195
