I might be wrong but,
it seems as though this is a website and the blog is in the /support folder and has the same look as the site itself..
If you want to add those pages to your site.. then rename the blog index.php to something else.. create a new index.php of your choice calling the blog into the interface or:
download the EzStatic Plugin and create yourself those pages and then make them links in your blog.
Hope that helps.
