If you're experiencing issues accessing your remote folder with Website Access Manager, the culprit may be symbolic links. A symbolic link (or "symlink" in geek speak) is a link that points to a different folder but doesn't actually contain the folder contents — kind of like a desktop shortcut on your computer. Website Access Manager cannot detect symlinks, so that's why you can't access your remote folder.
To correct this problem, you'll have to log into your hosting provider's control panel and create another FTP user account that defaults to the directory path your symlink points to. For specific instructions on how to do this, contact your hosting provider.
