I have a website: www.mywebsite.org
However, if any one tries to access it with that URL, they get a 404. Instead, they can get on with www.mywebsite.org/index.htm
The first time i published the site, i used a script in the index file which pointed to my homepage in another folder: www.mywebsite.org/homepage/index.htm
It is this second URL which pops up a 404, even though i replaced the script with a real index file.
Now whats the cause of this?
