Append/Restart not permitted, try again
Cause
The FTP server denies clients to restart/resume an interrupted transfer.
Solution
Enable restarts/resumes of uploads and downloads on the server side. You may need to contact the server administrator or the web hosting company to request this change.
Special Case: proftpd
By default proftpd denies clients to restart/resume interrupted uploads (AllowStoreRestart). But it allows clients to restart/resume interrupted downloads (AllowRetrieveRestart). This causes the REST command to appear in the FEAT reply and SmartFTP assumes that restart is supported. Thus SmartFTP tries to restart the transfer and fails because the FTP server doesn't allow it.
