I had same problem, reconfigured the fb-account on my N900 and deleted the device in fb. It worled after this.
Thanks for the reply but I dont understand what you mean by reconfiguring it. Ive uninstalled and reinstalled the uploader, ive deleted my account and revalidated it and ive changed my password on my fbook account and updated the change in the n900 settings but it still doesn't seem to work. During the upload it says transfer error and only like a couple of photos, if I'm lucky, get uploaded.
been experiencing this transfer error for almost a week now. i tried installing/uninstalling the app, revalidating, reboot and still getting the same result. i tried sociality too, even though the progress bar would reach 100%, photos still won't upload. any help would be appreciated.
I had this problem for a couple of weeks. I tried everything mentioned here first, but had no luck.
I was uploading to a facebook album with "custom" permission, namely "friends of friends". (I had been doing this with no problem for ages).
Uploading to "mobile uploads" was ok, as was albums with non-custom permissions eg. "friends only".
Changing the permissions of my album to "friends only" fixed the problem for me.
I also found that facebook albums have a limit of 200 photos, but no limit on the number of albums you can have - this is buried in facebook's help pages.
