After completing installation, there are a couple of important tasks to ensure your site runs smoothly and remains secure.

Final steps

Visit your website and go through its pages to make sure everything works correctly.

• Check for broken links, missing images, or any unexpected behavior.
• If you encounter any issues, refer to this guide for troubleshooting steps.

After confirming that your site works properly, it’s crucial to remove all installer files to prevent unauthorized access. A leftover installer.php file is a known attack vector, anyone who finds the URL could potentially re-run it and overwrite your live site, so this step isn’t just cleanup, it’s a real security requirement.

• Follow the steps outlined in this guide, “Removing Duplicator Files After Installation“, to delete these files safely.
• If the checkbox was marked during setup, the installation files will be deleted after your first login. Should they remain on the server, a warning will be displayed.
• If you didn’t mark the checkbox during setup, or the files weren’t removed automatically, you can trigger cleanup manually. The installer offers a “Remove Installation Files” action directly, and Duplicator also flags leftover installer files with a warning in the WordPress admin if any remain.

That’s it! By completing these steps, you’ll keep your site secure and running smoothly.
