Same exact problem here. I haven’t posted this month yet so I don’t know how long it’s been going on. Noticed 3 or 4 days ago that my plugins had all been shut off. Turned them back on — they have stayed on but tried to post tonight and it gets saved but won’t publish. Once it’s saved you can’t “save and continue editing” either. Either trying to save or publish, you get a blank page with no HTML on it in FireFox 2.0. In IE7 some simple HTML with an empty body is rendered.
The default admin user doesn’t exist — just me and I had a strong password. Changed it to an even stronger password and I noticed that once I did that, post editing defaults to showing tags rather than rendering HTML
Strange stuff happening here.
I’m still running 2.1.
