What is in the Current Webpage Preview pane is not found on the web.

Thanks Acorn I think I have been confusing myself however when I came to publishing the website as 2021blog it found the sub folder 2021bblog. Magix suggested deleting all the 2021 files and Exporting the website elsewhere so I transferred my site to an external hosting site http://www.pigsear.org.uk/2021blog.htm using Filezilla without a hitch (except I forgot where to save my files to!). Using Publish website option again went without a hitch.
Initiostar ponted out my coinslider errors on the http://www.pigsear.org.uk site which I remedied by replacing those with the error.
Thanks to everyone for your asistance.
