Q:

Copy the subdomain wordpress site into root directory of server with different domain

My project in subdomain(project1.com) i copied all folder and paste in root directory of server(project2.com) with different domain
But problem is when i change the text in my (project2.com)template changes show perfectly
When i logout from my project2.com  it shows the old text of project1.com 
I open the site in my mobile the text updated but in laptop it shows the project1.com text

i also use plugin for cache save the permlinks but it cannot work

A:

The problem is with W3 Total Cache plugin. You disabled it, but it served cache files. You should to activate plugin, delete cache files, then can deactivate it.
When you're in development, it's great to keep non-active all cache plugins to not have some issues with them.
