Hi - thanks for the help.
Via cyberduck, I'm still getting 'permission denied'.
Via Terminal, I'm getting the following error:
Permissions 0644 for '/Users/alexhadcock/Desktop/Live/new-ssh-key.pem' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "/Users/alexhadcock/Desktop/Live/new-ssh-key.pem": bad permissions
email@example.com: Permission denied (publickey).
Any ideas? As you can tell this is quite new for me - I'm used to accessing files via CPanel.
