Yesterday a friend contacted me about moving his site for Yahoo Small Business Web Hosting to another location. This typically can be challenging, regardless of web host, because of having to deal with someone else who has set this up and more than likely is not doing what they are supposed to be doing which is why the person wants to move the site in the first place. I was provided the Yahoo login information to the web and honestly had no idea how Yahoo Small Business has FTP set up. After logging in and searching around a bit I found the information I thought I needed and attempted to create an FTP user to login. After creating the FTP user I attempted to use the Yahoo FTP credentials in FileZilla to login but I continued to receive a “Critical Error” from the Yahoo FTP server. Below I describe the FTP error returned by Yahoo along with how I was able to work around the error.
