This is expected. You should not make assumptions about the state of the global Parser instance in a special page. In some circumstances (especially transclusions) it might be in a parse, other times it won't be.
If you're rendering an i18n message, its better to use ->parse() of the Message class then to pass it through the parser directly. Alternatively use \MediaWiki\MediaWikiServices::getInstance()->getParser()->getFreshParser() and then initialize it yourself by calling ->parse() on the Parser, so you always know what the state is for sure. -- Brian On Fri, Jun 11, 2021 at 9:27 AM Sebastian Trueg <tr...@truegeex.de> wrote: > Hi everyone, > > my skin uses the global parser in order to render some parts of the > navigation bar via templates (Parser::recursivePreprocess).
