Hi, I've used softaculous to install wordpress under my public_html directory.
However when I make changes or posts and wanted to view on the site (http://life-years.com/) I get this "404 error" page not found.

I also tried viewing it on http://life-years.com/wp (the default URL) , it give me the same error too. I am very new to web hosting or creating a website.

Would really appreciate your advise
