Hi Cornelia-I, I never doubted Jeffreys plugins and as stated already use them, but I have been using the adobe fb plugin since it was available and maintain about 40+ different albums, on my own page as well as other peoples pages where I have been given permission to do so. Transferring that to a new plugin would be a nightmare to maintain, fb doesn't allow modifying an image i.e. you can not update an image, it will just add a second version. So the situation, edit an image, check in the published collection, it hasn't been added (If it had it would be marked for republishing), add it. But if I used Jeffreys plugin I would now have to do that and then addit to the new Published collection for Jeffreys plugin!
Hence the reason I wanted to resolve the issues with adobes plugin, for me, at least!
As can be seen in my first post I actually deleted the prefs file (com.adobe.Lightroom4.plist) this did not change anything. But thanks for the reply.
