canvas page
Hello Dave and all,
thanks for this great module.
I must say first that I am new to both Drupal and Facebook application, and trying to build my first website on this.
I have tried previous versions of DFF (say, 6.x.1.x, 6.x.2.x) without problems on my dummy sites, and I must say everything worked great.
Meanwhile, I use the 6.x-3.x-dev version but the canvas page never display. It keeps reloading a white, blank page (except for the facebook bars on top of the page and the facebook ads on the right of the page).
So I change the canvas setting's render method (I know that it is going to be deprecated) into FBML and not iframe, and the canvas page is now showing these lines (apart from the Facebook bar on top and Facebook ads on the right.

Note: my website is a normal, newly installed drupal and nothing is actually there but a few paragraphs of 'lorem ipsum' text.
I do not have a clue what to do and where, so I'll just submit this issue here. I also aware that Facebook keeps changing their application all the time which makes some defaults, such as FBML tags, the SDK, etc. Yet I'll appreciate if I can receive some enlightments.
Additionally, I am happy enough with what this module have achieved so far.
Regards, Har-Ja

use iframe
Well the main difference between 2.x and 3.x, as far as canvas pages is concerned, is that in 3.x you have to use iframe canvas pages. You have to change your settings on the facebook side, to use iframe rather than FBML.
Also, get the latest copy of Drupal for Facebook. Some session problems have (hopefully) been fixed. See http://drupal.org/node/714018#comment-3285074
