I'm having similiar White Screen Of Death problem. I'm working on a host I've never used before. And it's Windows hosting, which I am not familiar with. My access is only through Dreamweaver. Using a Mac OS 10.4 (yes, I know: ancient.)
How I installed: uploaded a zip file to the root directory and unzipped it using a cpanel-style interface. This created a wordpress directory. I created the mySQL database manually, and edited wp-config.php manually. Then I did the install.php, and all was okay. I was able to log in, create a new theme, create several pages.
The symptoms: Originally, I was able to view the home page (at http://mydomain.com/wordpress/home), which was the "new" static home page in the Settings:Readings admin area. That was how I built the new theme (making css changes and php changes on Dreamweaver and uploading). Attempts to see other pages gave 404 errors. However, I figured once I put the WordPress index.php in place at root, all would be well. (I had an under-construction page at the root index.php.) However, when I did that, I started getting the White Page of Death. So I tried a bunch of things, namely:
1) moving the files to the root directory using Dreamweaver "drag it" functionality. More white pages of death throughout. Now even the home page is white screen of death.
2) deleting the entire wordpress directory and re-unzipping it from the .zip file. More white pages of death.
3) deleting the files from root, unzipping them on my computer, and uploading them "manually". More white pages of death.
4) removing all tables from database, redoing the install.php, and then uploading only the pages from the exported database file. (via an .sql file edited down from the original backup.) Still white pages of death.
I do not have any plugins installed. I even renamed the plugins directory. I have mostly always been able to log in and to access the admin pages. No white screens there.
Ah, yes, I also reactivated the Twenty-Ten theme. Still white screen of death.
Can anyone help? Thanks!
