@acrylian Thanks for the guidance.
I've tried "database refresh", but don't see a change.
I had seen warnings in setup about Litespeed, as opposed to Apache or Nginx. Now asking my web hosting provider, they don't support Apache or Nginx, so it will have to stay as Litespeed, if I stay on this host.
The image files are in the directories, as they always have been.
Do you have recommended procedure for a reinstall of some sort? (I've been relying on Softaculous for a while, although I could easily do something manually).
