The software for this site is periodically updated and typically this is a 60 second no hassle deal to apply.
Today's update put the site into a state where I couldn't complete but also couldn't revert back.
I wasn't getting a clear time of when I could get this issue resolved. Fortunately I had a good backup and there wasn't much posting going on this morning so I was able to complete a restore from approximately midnight.
Thus, if you posted anything of importance this morning, you will need to redo. Sorry for the inconvenience.
