WordPress "Future home of something quite cool". Plesk Windows. domain resolve to another IP address
I'm with Plesk Windows Hosting plan. Just removed a website and reinstalled this same website on Plesk and reinstalled it successfully but got this warning "The domain mydomainname.com does not resolve or resolves to another IP address(xxx.xxx.xxx.xx). Please correct DNS settings."
Since I don't know how to correct DNS settings so just ignored it. Then I installed WordPress under this path： home directory/mydomainname/, and use the default theme WordPress comes with and publish my website, but it's not my site but "Future home of something quite cool." I mean the URL is www.mydomainname.com but shows "Future home of something quite cool."
I've done a lot search around and found many people have got this problem since 2016 but seems no resolution by now. Somebody please please help!!
