Hello. I am trying to update the imagem from this section into my store. It was working perfectly fine just a few weeks ago, but now, suddenly, literally any image I try to place there will only show this weird black box (image with text overlay) . Only the text overlay works, and it won't matter which image I use (even the free suggestion ones, or the ones from my computer). I have already tried different devices but the problem still persists. I think it is a Debut theme related issue How do I fix it
You have to check in Section->feature-row.liquid file and find section.settings.image in <img> tag.
Or may be its hide by any css.
