All domain point main website

Hi;

I added second domain on my CWP. I can see the domain on list accounts. I use cloudflare for DNS. NS are correct and pointing CPW IP address.

I have A and B website. My problem is that B website not always open correct webpage. For example, If I visit Domain B it sometimes shows Website A and sometimes shows Website B.

Where i make mistake and how to fix it ?

Please go to Webserver settings > select webservers > select Nginx & Apache >save and Rebuild Configuration
