installing prebuilt website to a network
Before installing a new pre-built website, it is recommended to clean up your WordPress database.
Important: This tool DOES NOT create backups.
- Deletes: Posts, custom posts, pages, menus, categories, comments, etc.
- Remains: Users and passwords, wp_options, files on your server.
Comments
This is a standard message that shows every time you want to install a pre-built website.
If you want to install it in your subdirectory, this will not affect your main website.
But if you want to be safe, you can make a backup of your website using this plugin.
