I am trying to configue JobberBase but all the links on the pages redirect to 404 page not found error.

There are two scenarios...

1. If I put given .htaccess and admin .htaccess from docs folder; then i can't even open the main page. Whenever i type the url of the website, it just simple downloads some file.....

2. If I put default .htaccess and admin .htaccess (the default one provided in downloadable zip inside public folder), then i can open the main page and the admin main page aka. index.php. But then, none of the links work, and they redirect to 404 not found.
