I have NO idea what's going on. This happened to me with a beta test install a couple of weeks ago, but I neglected to mention anything at the time because I was too busy.
This time around, I have successfully upgraded an install to 2.0 (THANKS developers!!). Everything goes smoothly and all is well with the world. THEN all of a sudden I make a change and *Everything* goes blank--like no output of any kind; no errors, no HTML (on the page or in the source)--nothing.
Check it out: http://www.transreality.org
The server is running Redhat 9 with Apache 2 and PHP 4.2.2 (I know, I know, I'm in the process of upgrading).
Last time, the last thing I remember doing was activating Akismet with a WP.com key. This time, I was testing out the new upload feature in the "write" dialogue and after I hit enter, the form area went blank and nothing else appeared to happen, so I refreshed the page and it just went blank.
I'm at a total loss as to how to proceed. Any idea's would be greatly appreciated!!
