MediaWiki version: 1.36.0-wmf.18
The supplied ParserOptions are not safe to cache. Use NO_CACHE.
Conversion table pages are inaccessible for some language variants
The new ParserOutputAccess class will complain if asked to produce non-cacheable ParserOutput unless the NO_CACHE flag is given. This behavior was taken from the old code in WikiPage::getParserOutput(). It is now also being applied when coming from Article::view(), which seems to fail in the case of the conversion tables.
