My realm won't let me change the fire spreads to back on and I can't get it to let me upload a copy that works without an error.

Somehow "Fire spreads" turned off on my realm "Mighty Huffs"

 

I can't seem to get into a menu screen to turn it back on. 

 

I downloaded the world, turned it back on for my computer, and when I attempted to replace the realm with that version it keeps telling me there is an error. No error code or anything, just that it won't work.
