Nav menu links don't work properly

[danybr0]

I think there is an issue with the nav menu links. When I click on a nav menu link (for instance about-us) I get redirected to the localhost directory, when actually I should get: http://localhost/simple_php_website/about-us. I think it has to do with the website path which is not clearly defined.

I am runing to the same issue.
I solved it by:
If you are running the website in xampp, set your site_url to /yourfolder name in the config file
