I've managed to correctly install, run and see recent facebook posts using the plugin. However, it is getting a not-so-recent post... I've configured it to pull only one post and it is not getting the latest one.
I've tried some things that are suggested here and also tried using the FB ID for my personal profile, with the same results: it fetched the post, but it was a not-so-recent one.
Maybe this is an "order by" issue?
