facebook - Getting this error after months of no problems - redirect_uri not owned by application -

i had problem when started facebook integration of our site. after doing searching, found solution , fixed it.

now, few months later, has stopped working. nothing changed in either javascript code or app settings on facebook developers site. once again set searching, , found same answers before: site url must match redirect_uri etc.

i have app domain: "domain.com"
, site url: "http://www.domain.com"

error given:

api error code: 191
api error description: specified url not owned application
error message: redirect_uri not owned application.

i'm @ loss has happened. has facebook changed api? (i did check documentation, , it's still same).

any appreciated. javascript code below:

var publish = {     method: 'feed',     redirect_uri: 'http://www.domain.com',     link: 'http://www.domain.com',     picture: 'http://pathtoimage/logo.png',     name: 'name',     caption: 'title',     description: 'description, blah blah' };  function fbcallback(response) {     // stuff here }  fb.ui(publish, fbcallback); 

thanks

edit:
checked timestamp , js file hasn't been touched since 16th of march, neither has app settings on facebook, , colleague tested week ago (was still working then)

resolved:

for others having same problem, here's worked me.

it appears fb have tightened security, why working.
working on new release, , using ip address instead of domain access site. new message hadn't seen started appearing in dev console:

when using fb.ui, should not specify redirect_uri. 

looks fb api checks url domain in address field of browser (rather redirect_uri) against site url in facebook app settings. tested temporarily pointing our domain ip address, , running facebook api code via domain loaded site, , worked. while we're testing before release, i'll use http://localhost:8080 site url, update site's domain when goes live.

thanks people helped point me in right direction!
