I have never used this version of wordpress before, so this is new to me.
What happens is I create my database and upload my files. Edit/rename the config and upload that. I install and login with the given username/pass.
I can make as many changes as I want, view the site etc. AS LONG AS I AM STILL LOGGED IN.
If I log out I get 404s on EVERYTHING- but they aren't my webhost's 404's but Wordpress' 404's. I have found no remedy and have tried reinstalling from a different directory and brand new SQL DB, no luck.
I googled this problem and came up with references to .htaccess problems... so here is what mine looks like:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
