My nether portal isn't even lighting.

[crjase]

I have nether, fire spread enabled and I have a survival_nether world I created using multiverse. I go into my world called "survival" and I make a normal nether portal, try to light it and nothing happens, just plain old, cold obsidian.

If the issue is because I made the nether for my world using multiverse, then how do I get it to naturally make itself.
