Check original page, it opens a slideshow, which your template doesn't support at all. It's not a subdomain, the link you get is https://velvet.hu/galeria/velvet/kockahas/2019/01/15/a_cirque_du_soleil_totem_cimu_eloadasanak_probaja/ , it's just redirecting because of noscript. But even if it's a subdomain, it should be supported anyway - these galleries are linked from the articles, if your template doesn't support them you're missing a huge amount of content. If you have to open a browser to view the photos the article is about, IV doesn't make much sense, it ruins the experience. Check my template
