I am confused and need more information to be able to see what is going on. I checked the raice… domain and switched from parent theme to child theme. The list of pages stayed the same.
Themes ib WordPress can not have any effect on the pages:
I suggest that you give us a specific page with screenshots to know what is the difference between the parent theme and the child theme.
I also wonder what was the changes that you have done on the parent theme? Did you change any PHP code inside the files? If yes, you will need to restore the changes and move all your PHP code related changes to the Child Theme.
But if by changes you mean what you changed in Theme Options, it is very easy to move the changes to Child Theme, You will need to go to X > Validation while you have a parent theme and export the Theme Options and download the settings, then you can switch to Child Theme and import the settings from X > Validation.
Finally, I see that you have cache plugins. Please clear the cache and disable those plugins while you work on the website, as they may interfere with the correct showing of the frontend.
