What is the difference between FTP Remote Path and Website Base URL?
What is the Remote Path field?
The Remote Path field controls which folder the file is uploaded to on the web server. Depending on your website set up, this may be an optional field. Leaving the remote path blank means the file will be uploaded to the default folder your FTP account logs into.

What is the Website Base URL field?
The Base URL is used to derive a URL for a published web page. This value is not used when uploading and does not impact file transfer. The website base URL is usually always set to the domain address where you wish to access the published web page.
