Plot error: Error: Board stackup settings not up to date


I’m using latest build (see detail below).
I’m trying to plot gerber files, and I got the

Error: Board stackup settings not up to date.

Does anyone know what it means? This board is not stacked on another one,
and even if it was, I guess Kicad wouldn’t be aware of it, so I suppose there is another

This error happens just after plotting the edge cuts.

Thanks for any hint.

Thanks for your reply.
Opening and closing the board stackup setting solved the problem, but I didn’t do anything.

Can it be because it’s a 2-layer board and I have imported settings from a 4-layer board?


I don’t know. Anyway, it doesn’t matter unless you actually need it for something. The data is plotted to the gerber job file.
