Not sure what the heck is going on but all of a sudden Aperture 3.5.1 will not synchronize with SmugMug. I see the thumbnails via Aperture, but when I click on thumbnails no images appear. Nothing will even upload to SmugMug. Goes through the process but never uploads. Did disable and restart SmugMug plugin within Aperture, but again all I get is the thumbnails. I have Flickr setup and it works just fine.
Went to Lightroom 5.4 to upload images to SmugMug and all worked great.
I have no idea why it just stopped Synchronizing. Anyone else ever run into this issue?
