Hi, I'm trying to backup my web site from the server and use a backup plugin on the site and when I try to FTP the site to my hard drive I keep getting error transfering file related to this plugin and its folder...attached is a screen. I keep clicking on skip but is there a better way around this problem like don't back up this folder or automatically skip? Please let me know. Thanks!
