Still not resolved, this is a fresh install no plugins or anything. This same server runs a ton of wordpress installs so its not the server configuration.
Am having the same problem on a new install.
What I think is going on is that WP admin has become so bloated that it will no longer run in the memory alloted to us by the web host.
The webhost has the server set to not display the out of memory error so all you see is a blank screen.
Check and see if your PHP mem limit is set to 32m if its not 64m thats the problem.
I have tried putting the mem bump as suggested in htaccess and it did not work when I tried to put it in config it crashed wp.
What we need is someone to build a admin section thats striped down to work in the 32m enviorment.
Right now I am backung up and installing a older version to see if I can get a smaller version to run.
Just got 2.9.2 to work so thats the problem. v3 and up are to bloated.
Well I can not edit my other post so I will add this.
Here is what I discovered some hosts have installed blocks to stop scripts from changing memory limits. Some have also disabled the out of memory message. And this host I was using would cause PHP to die if you tried to raise the mem limit.
So when the admin script tries to raise its mem area to 256m PHP dies giving you a blank screen.
WP needs to fix this bug. the admin needs to be split into smaller scripts that can run with less memory.
