So have you ever seen Module:Unsubst working anywhere in an Wikia wiki?

So, I looked at where you copied the Module:Unsubst and from what I can tell it isn't used, so it probably doesn't work even there.

If you can find a Wikia wiki that has Module:Unsubst AND has a template that uses it and works, then I'll try to help you get it working. Until then, I consider that module incompatible with Wikia.
