incorrect url address

You don’t need “extension” blog.html.
If you don’t want the blog to show up at the root folder of your site – install it in a new subfolder of your choice.

thanks for that….i do not know how to go about installing it in a new subfolder of my choice..
can you please tell me what to do?

This should answer all of your questions…
