FYI: I have had an image waiting in line for publication (approval is done) for more than 24 hours now.
Maybe there is a cork in the bottleneck somewhere :-)
I have similar problems and have just commented separately in the "General" part of the forum.
This morning the site had few seconds of downtime. Some background server processes still need to start up again, but there is not a real problem. All approved photos are published right now.
Thanks Jay. All looks good now!
24 hours is minor compared to other sites.
