I´m trying to convert a standard post type to a post type gallery, but when I publish it, there´s no image on the top of the page so it is impossible to see the images as a slider
The images only can be seen individual at the end of the post
This is an example https://fpabloiglesias.es/inauguracion-todo-centelles-en-alcala-de-henares/
I have tryed to do it all brand new, but the result is the same: no image on the top of the post and no slider of images.
This other post type gallery was published on July, and then I had no problem: https://fpabloiglesias.es/hablamos-de-europa-la-transicion-ecologica/
