WordPress Categories 404ing. Whats the problem? What does WP require of the .htaccess
 

Ok, not only are my own wordpress categoriesgiving me a 404 now, but some wordpress installs I did through fantastico on another server are doing the same thing. Someone mentioned that it could be an .htaccess problem. I'm not seeing an .htaccess file at all on the fresh installs I did. What should be included in the .htaccess for wordpress?

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond &#37;{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

if when you change your permalinks and it says "You should update your .htaccess now" that's the code to put in there
