I am suffering with the same error. It’s been 5+ hrs i have been stuck on this!

Anonymous users should be turned off. Remove configuration for username ftp

Nope, same error.
I have been trying this for 10+ hrs now. Please can you help me

Start with a clean config file. You can get this from the tar file in the QBox directory or if you have backed up the original config file as instructed. Disable anonymous mode, enable local and write options.
This should serve milestone 2.

For milestone 3, use the config parameters provided in instructions.
