FTP is an insecure protocol and passwords can be obtained by hackers as passwords are submitted without any encryption. FTPS is a more secure protocol and we advise you to switch to it as soon as possible.
Please configure your FTP client to use "FTP over explicit TLS/SSL" to prevent any chance of compromise for your website at this time.
You may have to change the connection settings or hostname you connect to in your FTP client. All popular FTP clients support the FTPS protocol.
The hostname to connect to should be changed to FTPES://domainname.com (instead of FTP://domainname.com) or just domainaname.com
If you use Filezilla, please view http://wiki.filezilla-project.org/FTPS_using_Explicit_SSL/TLS_howto_(Server)
If you use WinSCP, please view http://winscp.net/eng/docs/ftps
For other clients, please consult your FTP client documentation on how to connect using FTPS instead of standard FTP
