I'm having problems hosting my last 2 websites, especially AchieversHouse.com.
The Shared IP address on my cpanel just automatically changed from 126.96.36.199 to 188.8.131.52, and I don't know how. So that when I set it the domain, it does not show the intended home page, instead the message on the page says "the people who manage this server have installed cPanel and WebHost Manager (WHM) which use the Apache Web server software and the Apache Interface to OpenSSL (mod_ssl) successfully".
I'm a bit confused, with how and where I could change my Shared IP address back to 184.108.40.206.
That generally means that the DNS has not propergated to the new IP Address. I would contact your host to find out why they changed it without notice. The bad thing is this can take up to 72 hours to complete.
If you run Windows - Try running this at the command line and try your site again to see if it helps "ipconfig /flushdns"
They would probably have moved you to a new server. They should not have done this without notifying you. I would contact them and ask them if they have moved your server, and if so why you were not made aware.
If the shared IP changed then they must have moved you to a new server. That default cPanel message will come up when changing ip's and your site is still propagating.You could try flushing your DNS by entering ipconfig /flushdns in command prompt, this sometimes helps speed things up locally.
