Your changes could not be saved in Library

Server Version#:7.1

When attempting to load my photos library for the first time (Newbie here) I got this message

“Your changes could not be saved.”

Why am I getting this error?

Pleas advise.

Short answer: the database is busy and changes aren’t immediately registering.

I’ve found that it’s often a false message — the changes take, they just take a while to register. That said, I’ve done times had to repeat it a couple of times. I default to try once and wait now, though, because deleting extra library copies is a pain.
