Mapped sites not loading support files

Hello, I have granted access to you guys. Amplifymycommunity.org is the main site; then there are multisites off of it, including AmplifyDecatur.org. The supporting CSS and JS files are 404 erroring; for instance: http://www.amplifydecatur.org/themes/sugar/schema/white_blue/css/viewset.css?ver=4.4.1

How can I fix this? Thank you!
