FireFTP error message 421
FireFTP was working great until I changed my Yahoo password. Now when I try to connect, I get error message 421: "Sorry, cleartext sessions are not accepted on this server.Please reconnect using SSL/TLS security mechanisms."
I changed my password in this login through the FireFTP account manager, and have tried manually entering it several times. I even uninstalled FireFTP and reinstalled, creating a new account with the new password, but I still get the error message.
Could this be a problem with Yahoo, my web host? I'm stumped! Thanks for any help you can provide!!

Sorry I couldn't be more help.
Looks that FireFTP tries to connect via a normal http or ftp instead of via a secure https or ftps connection to the server.
You will have to check the settings that FireFTP uses to connect in this case.

To use SFTP for a connection in FireFTP, select that connection from the drop-down list, click Edit, then on the Connection tab, change the drop-down from None to SFTP. The port should now say 22 (if not, change it to 22).
Oops, sorry, Yahoo wants FTP over SSL, not SSH. You should try one of the other 3 options in the connection/security drop-down starting from "best" and working your way down.
