After upgrading to LR4.1 it is not longer possible to upload photo's. I removed the up in facebook and was able to make a new (validated) connection but that didn't help.

Sort it out. Something changed in my facebook settings (and I did not do it). This is wat was changed:
Home > account settings > notifications > all notifications > other applications > checkbox Adobe Photoshop Lightroom was not checked anymore. Check it and everything is OK again.
I ran into it again today. I ended up deleting the album on FB, going back to LR FB Publish Services for that collection, and did Edit Collection to set the album up again on FB. Then I marked all the previously published pics for re-publish and did "Publish Now". I got one "upload failed" pop-up, repeated the "Publish Now" and this time everything (new and re-publish) was uploaded. I had to go to FB to delete one pic that was duplicated by the failure/repeat sequence. I wonder if FB albums have some hidden attribute that confuses LR?
