Gallery show single images | WordPress.org

I didn’t have this problem in the past.

In my last article I added a gallery of 9 images but if I click on the first one from the article, there is a direct link to the file and the window that allows you to move to the next image with the arrows does not appear.

In the gallery link settings there is media file and I haven’t touched anything.

I use webp images and realized this happens in all my old galleries too.

I remember well that it worked for years without problems.

Now it’s a problem because the image takes up the entire page and you have to go back to reload the entire site.

You can set to open images in a new tab but I have to do this for each gallery.

What could have happened?

Thank you
