I actually need to add in all my categories. I'm sending the images straight from my computer (as I've always done) But I tried to add images uploaded to my media admin panel and it didn't work either.
There in the panel, the images that I add appear normally. The question is to appear on my website, as always the ones I added are there.
The strangest thing is that when I create a new category and add an image to it, it appears normally on the site. Only the images that I add in the existing categories do not appear on the site.
Attached to the image an example. The product that is circled in red, I just added it, however, it does not appear on my website
