The domain you have requested is currently not in use under an x10Hosting web hosting

[gemstones]

whenever I try to open my webpage on
http://gems.x10.mx/
I get an error
"The domain you have requested is currently not in use under an x10Hosting web hosting account."
Same is the case with my webpage
www.mahavirgems.co.in

For http://gems.x10.mx/, I can visit it just fine. Please try deleting your browser's cache and flush your dns.

As for mahavirgems.co.in, you'll need to go to your domain registrar and change the primary nameservers to ns1.x10hosting.com and ns2.x10hosting.com Allow for dns propagation and then it should work just fine.
