Trying to update my Smugmug page for the first time in a long while (since I got LR4).
Everything seems to work, and it does create the gallery in Smugmug, but after waiting for a couple hours with the progress bar moving very slowly, I get a popup box which says
"The server returned an invalid or unrecognized response."
with every photo I tried to publish listed. When I check smugmug none of them have uploaded just an empty gallery. Is this a software problem, or perhaps a bandwidth problem? Any help?
Have you configured the Smugmug plugin? See here
for instructions. I have uploaded full sized jpegs from the Nikon D800 with LR4 and the process went smoothly.
