Can't translate bones

Hello!

I’ve got an armature where it is impossible to translate rather than rotate bones.
I’ve seen that some people suggest toggling the “Manipulate Center Points” button, but that makes it so that I can’t do anything with the bone I’m trying to manipulate; no rotation, scaling, or translation.

Might anyone have any idea what I should do that would allow me to translate bones? I’m aiming to set up some IK.

Thanks!
