You have an extra comma in your JSON - you're not allowed a comma before the close-brace.

Change

theme_advanced_resizing : "true",

to

theme_advanced_resizing : "true"

and it should work

Thanks for your post. Saved me a lot of time. Old habit from PERL programming, still it's IE's fault... ;)

Great find! Found 4 other solutions that didn't work. Felt this was too simple to be the problem, but it was. Tricky little commas!
