1. You should change your File Browser path at your setting to a path with slash
that means don use Backslash for example : C:\vhost\domain_com\
you must use : C:/vhost/domain_com … (no ending slash)
Don’t worry it will work. I had the same problem with the milion of \\\\\\ in Filepath after you add the file it will not happen again.
After that you maybe need to remove the file and add it again.
Now you can check it even if you change the Download Site it will not add slashes …
2. You need to change or make a own template.
Inside the Template you maybe have [file_list] … Remove it and the File information should be gone.
Hopefully i could help you.
Maybe someday i get help for my questions too.
