    After upgrading to WP 4.9, this plugin no longer works on my installation, claiming:

    PHP Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'Closure' is not allowed' in ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Crypt/Random.php:156\nStack trace:\n#0 ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Crypt/Random.php(156): serialize(Array)\n#1 ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Net/SSH2.php(1251): crypt_random_string(16)\n#2 ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Net/SSH2.php(1075): Net_SSH2->_key_exchange('\\x14Nf\\xE1\\x8E\\xB1\\e\\xEA\\x8BI\\v\\xFA;\\x98>...')\n#3 ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Net/SSH2.php(1869): Net_SSH2->_connect()\n#4 [internal function]: Net_SSH2->_login('user', 'pass')\n#5 ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Net/SFTP.php(431): call_user_func_array(Array, Array)\n#6 ***/wp-content/plugins/ssh-sftp-updater-support/class- in ***/wp-content/plugins/ssh-sftp-updater-support/phpseclib/Crypt/Random.php on line 156

    Note also that this logged output reveals the password, which is another bug (I have substituted in the word ‘pass’ above.

    Update! The plugin works now if I update the phpseclib directory within wp-content/plugins/ssh-sftp-updater-support with the version 1.0 from https://github.com/phpseclib/phpseclib/. I did this using 

    curl -L -o phpseclib-new https://github.com/phpseclib/phpseclib/archive/1.0.zip
unzip phpseclib-new
mv phpseclib-1.0/phpseclib wp-content/plugins/ssh-sftp-updater-support/

    Could someone update the plugin with the latest phpseclib-1.0/phpseclib folder?

    Hilarious typo there. I meant this *works* for me now. Thanks.
