All was working fine up until earlier today when I tried to upload a very minor text update to my site when I received this message.
I've restarted both MAC and Dreamweaver and switched of router for a few minutes both to no avail.
Once again any help would be greatly appreciated.
Kind regards, Garry.
I have also tried this suggested solution without success.
Did you try connecting with a dedicated S/FTP client like Filezilla?
Failing that, contact your web host. They may have upgraded or changed server settings without telling you.
