So, I had an expression with: x = 100*targetX/thisLayer.sourceRectAtTime().width;
which worked just fine on my machine. But running it on a server gives me expression error: "expected ;"
I resolves with putting space after slash: x = 100*targetX/ thisLayer.sourceRectAtTime().width;
I don't know much about the server: it appears to be Windows-run and it renders with aerender automatically.
So I hope there's someone who has encountered this before and could explain what exactly is going on here.
