Thanks guys!

Changing the bootstrap url from "/latest" to "/3.3.7" in two places (src/client/account/settings.js and src/middleware/header.js) gave us an immediate fix to this problem.

And just random kudos for how easy it is to find and fix things in NodeBB. Definitely my favorite forum software!

Minor FYI....Elasticsearch has made a strong stand that they are not a database. There are certain levels of consistency and reliability to qualify as a database that they have said they cannot support. But if your data isn't critical, and you don't mind a noticeable a delay between when you write a document and when it available for reading, then that's fine.
