Hi,
Check if the pre-built website pages are still available in the WordPress trash folder. Go to the “Pages” section in the WordPress dashboard, and click on “Trash” to see if the pages are there. If they are, you can restore them to the “Pages” section.
the pages are not in the trash folder, try reinstalling the theme and importing the pre-built website again. Make sure to follow the instructions provided by the theme documentation to import the demo content correctly.

If you still cannot edit the pre-built pages or create new pages, try disabling any conflicting plugins or settings that may be interfering with the theme’s functionality.
Note our dummy content works only on a fresh installation. If you have some content already it will conflict with your existing posts and most of the content will not be imported correctly.
Best Regards.
