EXTRACT INTO public_html (important)
====================================

The zip contains a folder named nextukconsultant-cpanel.

WRONG (causes /public_html/ in the URL):
  public_html/nextukconsultant-cpanel/...
  or leaving a nested public_html folder

RIGHT:
  1. File Manager → open public_html
  2. Upload nextukconsultant-cpanel.zip and Extract
  3. Open the new folder nextukconsultant-cpanel
  4. Select ALL files/folders inside it (index.php, app, config, …)
  5. Move them UP into public_html (so index.php is directly in public_html)
  6. Delete the empty nextukconsultant-cpanel folder and the zip
  7. Visit https://yourdomain.com/install.php

You should see:
  /home/USER/public_html/index.php
  /home/USER/public_html/install.php
  /home/USER/public_html/app/
  /home/USER/public_html/config/
  …

NOT:
  /home/USER/public_html/public_html/index.php
