On page https://factinfiction.meulie.net/Vixen_03 I have the following code:
<include noesc nopre src="https://en.wikipedia.org/w/index.php?title=Vixen_03&printable=yes" />
This should include https://en.wikipedia.org/w/index.php?title=Vixen_03&printable=yes, but it looks like it includes https://en.wikipedia.org/w/index.php?title=Vixen_03 instead.
What am I doing wrong?
