Lost site layout

I’ve been using the Newspaper theme for quite some time. This morning my website at https://k5nd.net/ lost all formatting. When the site first comes up, there’s a brief glimpse of the proper layout, and then it just spews the content down the page. This happens on all pages. I’ve restored the site from a backup, but it’s still the same problem.

Here’s what the home page should look like.

Here’s how it looks at present.

I’ve dropped back from version 12.6.4 to 12.6.3. That didn’t fix it.

I’m open to other thoughts on how I can fix this. Thanks.

Hurrah. Found the issue. I started turning off plugins that were recently updated. I found that the Sassy Social Share plugin caused the problem. All back to normal now.
