I am using BlueHost and what I did was simply go to the CPanel and choose WordPress from the Software and Products section. Right now I want to create a theme and to do that I must have an FTP client. I don't know my information like my host, port, and username and password. However, I did try it once and it connected but then every time I copied something to my site (with FileZilla) nothing showed up. Perhaps I am using an incorrect host or something.
