Config prob? - prod app trying to pull assets from localhost

I just got deployed for the first time w a new (to me) hosting
provider yesterday with an evolving app on a project for a client and
one thing I still am having pros with is that all the assets the app
needs (image, css, and js files) are not being accessed because the
app is trying to get them from localhost.

Firebug shows the following kind of thing within the script tags as
the src for the JS files:

src=“http://localhost:3000//javascripts/prototype.js?1257382712

I havent seen this before on other apps I’ve deployed elsewhere… I
cant see anything where my config is hardwiring this or anything.

So, here are my thoughts and maybe someone can tell me if any of them
look to be the cause:

  1. it’s me - somewhere I have screwed up my configuration within the
    app itself… maybe someone has suggestions where to look

  2. it’s the hosting provider - in the sense that there’s something in
    my deployment with the host that I got wrong… again, any ideas of
    where to look? (I know this could be hard to answer 'cause I’m keeping
    the hosting provider nameless)

  3. it’s DNS - I say this because the client hasnt set up DNS yet
    (stealth mode thinking) and the app is being reached by typing in the
    IP addrs… could this be causing the app to look to localhost? not
    sure if that’s the way things work and the app goes from page to page
    using the IP addrs as the domain vs localhost (which it only seems to
    do for these assets)

hoping someone has seen/fixed this before or just knows more than me
and can help

OK, it was me, but I’ll share for anyone else who may come
across this…

I’m using the facebooker plugin. it has a config file
facebooker.yml… that has the following settings (amongst others):

development:
callback_url: http://localhost:3000/
set_asset_host_to_callback_url: true

It has separate settings for production… can you guess?

I neglected to change that callback_url for the production environment
after I setup the static ip addrs with the hosting provider!

Also, for a FB Connect app you should set
set_asset_host_to_callback_url to false.
