I decided to try 76 RC, but was surprised to find that my startup page http://localhost/index.php does not work. Instead, it is changed to http://www.localhost.com/index.php, and then it is reported that the URL does not exist.
My KM 76 RC2 does not change the name, but does not find a file. Of course I do not have a localhost/index.php to be found. Physically, where is your file?
