how to change a wordpress home page permalink as referenced in submenu links
Go to All pages from Dashboard and find the parent page of your subpages site-map and privacy-statement. It must be named Home( your front page now ). Then hover on it and click Quick Edit.
You should saw something like this: 
Change the slug from home-2 to home( I marked that field with red underline ). And click to Update button. Your subpages will have permalinks like so now:http://localhost/mysite/mysiteWP/home/privacy-statement/http://localhost/mysite/mysiteWP/home/site-map/
Note, that you can't save page with slug home, if there is another page with same slug in the Published, Draft, Scheduled categories.
