I've had a number of excel files saved as 'web pages' (.htm) for years with difficulties. In the last week I have not been able to view those recently updated htm files on my website, instead I get "Sorry, the page you're looking for can't be found" homestead page. The file is there, it saves and publishes fine but no longer visible online. Why is this file type no longer working? Sitebuilder no longer works on my XP system so I've been forced to use Sitebuilder Plus, which has been painful and unreliable at times but has been adequate. Until now?
