A user has created an account and i have given him access to a cpanel. He gave me the domain and everything is working now. However, when he tries to visit the website and open up links, it automatically adds his username e.g.
www.domain.com/~username/contact-us
Now, when he removes the ~username, the page still shows and its all working.
this is his htaccess file: http://pastebin.com/M8xmg8er
