New website wont open,why?


I can’t get my new website to open. (i buy new domen)
I can open it with dashboard,and see everything. I built site from Chrome, and when I want to open any category, there is 404 error.
But when I want to open with another browser,it looks like this.problem


Looks better here?
Maybe try CTRL + F5 on your site and report back?
