Yeah. I did run upgrade.php. I had a few problems, but it managed to fix itself with a bit of tweaking. This seems to be affecting only one user. Not sure if its a browser related issue or something that others have come across?

However…

That (very different problem) has nothing to do with my issue. Please don’t disregard this question based on the fact that someone else piggybacked… !

So, lovely.

tdw’s suggestion had me thinking. So I updated the file and still an error. Oddly enough, the idea of permissions struck me. Some php files seem to be kosher with 6xx (which seem to be the standard permission sets). _HOWEVER_ when I randomly went ahead and changed the permission (to cheat, I just changed it to 777, but I’m sure 755 will be sufficent) on related_posts.php and, lo and behold, no more errors! Sure enough, doing the same to the other problem files, makes everything work. So the answer to my question all comes down to permission errors. Yay!

WordPress still rocks, thanks for the help.

I tried, just for the giggles, to change the theme to WP classic, with permissions for the whole directory being 777. No love, same errors.
