Append/Restart not permitted, try again
Problem
You may receive the following error message from the FTP server when trying to transfer a file:
Cause
The FTP server does not allow clients to restart or resume an interrupted transfer.
Solution
Enable restarts and resumes for uploads and downloads on the server. You may need to contact the server administrator or web-hosting company to request this change.
Special case: ProFTPD
By default, ProFTPD does not allow clients to resume interrupted uploads (AllowStoreRestart), but it allows clients to resume interrupted downloads (AllowRetrieveRestart). This causes the REST command to appear in the FEAT reply, and SmartFTP assumes that restart is supported. SmartFTP then tries to restart the transfer, which fails because the FTP server does not allow it.
