Page Attributes Dissapear

My blog is https://www.newarkohiogardenclub.org.

I went to add a page and the attributes panel has dissapeared. It was working fine up until a couple days ago, so the templates are fine and the theme is fine. I’ve deleted all the plug-ins and I’ve tried activating an older version and WP’s default theme then going back to mine and it’s still not working.

I found a forum talking about the div “pageparentdiv” but mine is display: block, which should be fine.

I haven’t updated WP, so I’m not sure what the problem is.
