I’m not sure how I would do that with a shortcode. Or if that is even the issue here. I turned off header BG color but still no slider in that language, sitewide. Ideas?
edit: solved. Not theme issue, polylang tries to “translate” your media by default. It hides the whole media library from posts and pages unless you RTFM. Yes, it tries to translate your images. Go to polylang settings and read carefully.
