I’ve opened nashira.dreamhost.com using filezilla. All the wordpress stuff is there. Now how can I access it and see the basic wordpress install?
It sounds like you are doing a manual install.
If you are not familiar with wordpress, I’ll suggest you to install wordpress via DH panel --> Goodies --> One-Click Install --> WordPress.
Otherwise, please refer WordPress installation guide.
To start installation, it should be something like nashira.dreamhost.com/install.php. Good luck!
