whois life-crisis.com indicates that your registered nameservers are:
ns1.prolinkhosting.com ns2.prolinkhosting.com
nslookup life-crisis.com on either of these two nameservers gives "server can't find life-crisis.com: SERVFAIL"
You might want to contact the company providing your domain name servers and ask that they be set up to return a valid IP address for life-crisis.com
The domain is indeed registered with dynadot, but no working nameserver = no website. If you're seeing anything in your browser at all, it's because your computer or your ISP has a previous version of the domain address info cached somewhere.
I'd suggest that you contact your webhost; you've misconfigured something there.
