I want the border on top rather than bottom for archive and blog pages. I see the changes in the admin Editor under Appearance. I see the changes when I view the file through FTP. But when I click on the stylesheet link in "View Source", or view in the inspector, the changes aren't there!
Problem was solved by contacting Hosting Provider. I'm hoping the solution will help others who may have an file updating issue and have not yet updated their WordPress Core to 4.6.1!
