[problem] register website hosting

Hi there!

I have some problem with hosting my server website. When I start hosting in WebServ it seems to be alright, but it's not. On my PC it's OK, but when my friends try to enter website.. it displays "This URL is crashed." or just white blank. Wtf?

Greetings

Youre Friends must enter into youre hamachi network.

If not, the website dosen`t load the register page.
sry for my bad english.

My friends are in my hamachi network. Yesterday website works good, and all was OK. But today, when my friends try to visit this website.. browser often displays white blank or "This site is crashed".

I tried to upload other register pages, but it still not works :/. Help!
