Well, now I know that auto-updates are not a good idea. Now.
After completing the last (3.8.1) update, my plugins do not display in the admin of my network, instead, I see this:
"You do not appear to have any plugins available at this time."
Also, I've created pages and uploaded photos, however while they appear fine in the admin view of my sites, they do not update at all in the front end. It's as if they don't exist when visiting my sites.
My network is simply two versions of one website, one in English and one in German.
If anyone can help with this I would very much appreciate it.
