The good news is that either cPanel, CSF, or Filezilla decided to finally play a little friendly. To fix the Filezilla MLSD on cPanel servers, you just need to add this to your CSF firewall:
Allow incoming TCP ports TCP_IN =
Add this after all the numbers listed there:
,49152:65534
Then restart the firewall and Filezilla should be fine. If they decide to not keep this easy fix going, you'll need to access this file:
nano /var/cpanel/conf/pureftpd/local
And change the PassivePortRange line to:
ForcePassiveIP: ~PassivePortRange: 49152 65534
Last you'll need to reboot the FTP server.
Sometimes Nano will not edit the file (/var/cpanel/conf/pureftpd/local) in which case we suggest an SFTP program like WinSCP to edit it.
