Author box stopped working

Hello! I had set up my WP site with three users who were all me (can’t remember why). I didn’t like the particular version that the Author Box block was picking up, so I deleted 2 of them. The remaining user is the Admin, and all posts are attributed to it.

But now the Author box isn’t picking up anything – no photo, no info.

How can I fix this?
Thanks,

Hi Vlad,
Thanks but that didn’t help. This box was working fine before I deleted the extra users but now it’s not working at all. It won’t even load a header for the the block!

Here’s a screenshot: https://www.screencast.com/t/1lIyRnKhh

The author ID in the screenshot is sort of covered by a LastPass button overlay but the correct author ID is in the box under that overlay.

Also I am having another BIG problem with the site – on my own computer, when I’m logged into WordPress, all the images load fine. But on Other computers and mobile devices the images are not loading.

Here’s a screenshot of that same part of the page, where I’m not logged in: https://www.screencast.com/t/VYna7G8yc

Images are also not loading on post pages.

What can I do to fix this?

Newspaper theme and tagdiv are totally new to me so I am at a loss as to how to fix this.

Thanks,
Kathee
