I'm sending the address to my domain www.omeroliel.com and some of my friends say the domain doesn't work with www, without www, on IE, FF, and some reasons like that.
Sounds like your friends are experiencing caching problems either with their computer or with their Internet Service Provider (ISP). We've checked your domain, and we can see your website for your internet business.
More information about caching problems can be found here:
You can do an IP lookup in your Dynadot account to see if your new name server settings have been propagated through the system. If they haven't propagated yet, you'll see a "name servers misconfigured" error.
The website or the old name server settings for your domain are cached.
If you aren't getting the "name servers misconfigured" error in your IP lookup, you can try refreshing your site a few times. If that doesn't work, you can try clearing your cache. Click on "cached" above for more information & browser instructions.
Your web host has not set up their name servers to handle web requests for your domain yet.
We recommend contacting your web host about the issue.
