I resolved the issue. When debugging, I noticed that in the file "/community/cache_public/bx_templ_js_ ... .js", there were a bunch of 401 Authorization Required errors in the place of the actual javascript file source (see end of posting for details). Seems like the server was trying to include these files but wasn't able to.
These errors were caused by the directory protection (using .htaccess) I applied at the top level (/community) to keep the /community path private until it was ready for production release. It seems that the the server requires the authentication credentials when trying to include these files even though I authenticated on the client side. To fix it I've removed the .htaccess style protection and will just rely on protecting the site by preventing users from being able to login until the site is ready.
