When I signed in today, the login screen told me there was an update to the database that had to be installed. I clicked OK, and went forward. The backend is now updated--it looks quite different. However, many of the features have stopped working.
When editing posts, I can no longer add links using the link button. In the Publish box in the upper righthand corner, I can't modify anything--status, visibility, or when it is published. In fact, I can't even get today's post to publish. I tried all three browsers on my mac, and nothing. The second site I run on wordpress hasn't undergone the update, and it's working just fine.
Thanks for any insight!
