I have installed WP using fantastico on hostgator.
I installed it into the site root (example.com).
Fantastico created a wp-config.php file for me. It includes a db name, db username and a password (auto generated, I assume as it looks something like this: XWDf235Sfsd23cblA
The installation went fine, only when I look at either example.com/wp-admin or example.com, I get a 404 Page not found error.
who knows a reason for this? (i have read heaps of other forum posts but did not see the answer).
