That’s very odd - can’t think of any kind of cache that behaves like you described. MySQL query caches are expunged if the data updates, filesystem caches would be irrelevant, and by default web servers don’t cache at all. So unless they’ve snuck in a special invisible wordpress cache plugin (perhaps in mu-plugins?) no idea where it could be happening.

If they’ve said “use the terminal” what are they actually telling you to do in the terminal? And is “server cache” explained anywhere (the term by itself is meaningless)?
