Bones will move but not rotate v2.8

I watched a couple videos of how to add the human rig to a figure. Pixxo’s is the one that was most helpful here:

All of the bits and pieces move using G, but they will not rotate when I hit R. I get the black dashed line like it wants to rotate but nothing. No luck after searching for the solution. Here are 2 relevant screenshots.


When I opened the file today this msg appeared:
Also, there are bones that will not move.

Why does everything have to be so hard…?
