I cannot access the ftp site of my client after installing you
last 2 versions. I accept the security message and then I cannot

Your server is behind a NAT router. Neither the server nor the NAT router are configured correctly for FTP over TLS.

Contact your server administrator or server hosting provider for assistance so that the server configuration can get fixed.
