After installing and setting up Ikiwiki on my Debian server. I somehow got the following error when trying to edit index page in browser / online: Not Found The requested URL /foobar.com/static/ikiwiki.cgi was not found on this server. Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. My `foobar.setup` has the following for CGI configuration cgiurl => 'http:/foobar.com/static/ikiwiki.cgi', cgi_wrapper => '/home/foobaruser/foobar.com/static/ikiwiki.cgi', What could be wrong?
