If you're having trouble getting the template to work with the new sugarcube update, here's what I did to fix it:
Go into 'StoryInterface' and change the word story in <div id="story"> to something else (I changed it to 'mystory'). Then, go into the stylesheet and change every 'story' in the stylesheet to whatever you renamed it to.
If after that, you're running into the error where it says there's a problem with 'config', do what Douve said, just capitalize 'config' in Javascript.
You might have to fix some design elements, but hopefully, this fixes the major issue for you.
