If you've been by in the last hour or so, you probably noticed you'd gone blind or something. You knew it would happen eventually. Or not--seems it might have been a "computer" error.
Movable Type is acting strange and annoying. Not necessarily MT's fault though, given the weird setup we have.
Anyway, a bunch of blogs went blank. Rebuilding them was... iffy. I have no idea why that is; it was working; it should have worked.
I went and reset all the permissions on the MT2.6 blogs to something simpler, and rebuilt the ones that are listed below, and they all seem to be fine now. (Munuviana went blank somewhere along the way, so I rebuilt that too.)
If your blog has gone blank, either edit and save your most recent post, or go into Rebuild Site and choose Rebuild Indexes.
