I've got a couple of weird things going on:
1. When I try to make any changes to my theme files using the built-in WordPress editor (in the admin control panel), the system just cycles and cycles (hangs) and doesn't save the changes.
2. The name of my site has disappeared in the upper left corner; now all I can see are three ellipses (or one ellipse; three dots).
I'm using WordPress 2.8.5 on Aplus.net and they just upgraded our servers. Any idea what might be wrong?
