Website not showing up on safari mobile

I don’t have Safari handy, but I can see that unencrypted files are also loaded when loading. As a result, I also see a warning in Firefox. You should check that out. Among other things, this image is not included via https: http://abdex.com/wordpress_abdex/wp-content/uploads/2019/09/hoses.jpg?id=2722

Maybe that’s why Safari refuses to display it.

However, the question would also be what you see exactly in Safari. I can’t imagine anything under “will not appear”?
