I am a noob at web hosting, and I want to create a custom 404 error page, I read the wiki, and I don't have a htaccess file! What do I do?
Create one! It's just a text file named ".htaccess" — nothing at all fancy about it.
You just create one with a text editor! There is no default .htaccess file in your FTP space.
This might help:
You don't even have to mess with .htaccess. Your custom 404 page should be named missing.htmlhttp://wiki.dreamhost.com/Creating_custom_error_pages
