Very interesting! I didn’t think to open the pdf on WordPress to check because it did and does display as the black version in the Library. But I just opened it and, sure enough, it looks fine. So it’s baffling but I guess it’s a display glitch that will, hopefully, get resolved. Thanks!

Thank you, Erica! That’s absolutely it, and I knew that setting but forgot about it because I hadn’t changed anything. Maybe it got changed in an update? Anyway, I’m now all set, thanks again.

Same problem here and it happened at the same time. And I’m pretty sure my theme is up to date. Can someone help?

I realized there’s one other way to go “just core” and that’s to clear the cache; I did and the problem went away. How strange are the ways of the computer Gods. Anyway, thanks for the fast response.

When I went to the Plugins page, I discovered this message:

The Advanced TinyMCE Config plugin requires attention: you are running TinyMCE 4.0 (WordPress 3.9 or newer) but the settings for the editor have not been updated. This can result in errors while editing, or the editor may fail completely.

The problem with that is that it doesn’t indicated what settings need to be updated and to what. I click “Advanced TinyMCE Config/Edit” and there’s nothing that seems obviously editable.

However, in “TinyMCE Advanced”, under “Advanced Options”, there was this:

ERROR: Your theme does not support editor-style.css. To use this option, add editor-style.css to your theme or a child theme. Enabling this option will also load that stylesheet in the editor.

It looks like this may be a problem with this specific plugin. I’m no coder, though; I have a tech person who does things like this. Would you say that this is a plugin problem that the tech person has to handle, rather than a WordPress issue?

Thanks, but before doing that: given that this problem occured directly after a successful edit, and I haven’t added any plugins or themes for weeks, is it still possible that’s the problem?
