I am trying to use the FTP uploader to upload a site to Bluehost. This box keeps popping up, even if everything is entered correctly. Any ideas or suggestions???
Can you please try exporting your site as HTML and uploading your site via any third party client like Filezilla or Cyberduck and see if the credentials work out there?
If they don't work then you will have to reach out your host and check on this.
