Story Map Cascade hosted on web server does not load in browser

[aaronISGGIS]

Cannot get Story Maps Cascade to go beyond the loading GIF after being deployed on web server. I worked with Esri Technical Support who suggested I raise the issue here after they were able to replicate the issue with multiple deployments on several different machines. Don't have a ton of additional information, but the bootstrap-overide.less is giving me a 404 error. Let me know if you need any additional information. Thanks!
