New domain is not working properly!

So i bought domain example.com and decided to use it instead of example.hosting.com While using example.hosting.com it seems everything works fine on my blog, but when i use example.com url wont change no matter what page i click, it stays the same example.com .However, if i write example.com/registration it redirects me to registration page, but url stuck on example.com/registration while browsing through another pages or posts.
