I'm sure it is something stupid, but I'm having issues logging into the root using Filezilla.
I created an FTP access user in admin. I set permissions as FTP. I created new password (let system create it). Try to log in. No good.
Command: USER XXXXXX
Response: 550 SSL/TLS required on the control channel
Error: Could not connect to server
The odd thing is, we created a subdomain to test the WP site we're developing and if I point my ftp to that domain, subdomain.mainurl.com it logs in fine, except it shows no files (even though that's where we installed Wordpress).
