Where are you actually trying to publish it? Any specific service like Facebook, Hard Drive, Flickr?
You can check if the Publish Services are configured correctly from Publish Manager found under Library Module > Publish Services > Drop Down option (little + sign) > Go to Publishing Manager
If you want, you can delete that service and re-add it and then check the same.
Let me know how it goes.
Hi, publishing to Flickr, I have already done what you suggested a couple of times on the computer treadmill, no luck. Thank you.
Which version of LR? Mac or Windows?
Recently there have been a number of reports of LR 4 and 5 Flickr publishing no longer working. (It works fine for me, at the moment). See this thread for a workaround:
Re: I've been using Lightoom 4.4 now for a while and i've always been able to load straight to Flickr. I clicked "authorize" over and over, yet the website doesn't open up where i click to authorize it. not sure where to go from here
I'm running 4.4 and get the same runaround
The solutions in the thread I referenced are working for others. Maybe Arpit from Adobe will have a different solution for you.
