I've had one domain for a while and I used WISE-FTP for it and it worked well and everything.
But now I bought another domain and I got a separate FTP account for it, but whenever I log into the new FTP account, it still shows the files and everything from my first website, and when I type in my new website's URL, it re-directs me to my first website.
If I tried deleting some of the files that were from my first website that were on my new FTP account, but those files were also deleted from my first FTP account.
I don't think it should be doing this, especially if they are two different accounts.

Does anyone know why this is happening or how to fix it?
Thanks!
