THE ADAM COMPANY ERP - PHP 8.3 / MODERN UI PACKAGE
==================================================

Purpose
-------
This package upgrades the supplied Core PHP ERP for PHP 8.3 while preserving
the existing workflows, calculations, URLs, database tables, and print layouts.

Main changes
------------
1. PHP short tags converted to portable PHP tags.
2. Removed PHP 8.3 startup fatals from the legacy PHPMailer autoloader.
3. Removed calls to the deleted get_magic_quotes_runtime() function.
4. Corrected the shared database wrapper to count SELECT result rows correctly.
5. Corrected the mysqli connection argument usage.
6. Corrected string-based error_reporting(E_ALL) calls across application and print files.
7. Disabled public display of production PHP errors while retaining server logging.
8. Added a shared responsive modern UI for forms, cards, navigation, tables,
   reports, login, buttons, dialogs, and mobile layouts.
9. Added print CSS for browser-printable screens.
10. Disabled directory listing and direct web access to common backup/data files.

Installation (cPanel)
---------------------
1. Back up the current Adam ERP files and database.
2. Select PHP 8.3 for the target domain/subdomain in MultiPHP Manager.
3. Upload the upgraded ZIP to the document root and extract it.
4. If the URL should contain /sales, retain the included sales folder.
5. Update sales/classes/config.inc.php with the target database credentials and URL.
6. Import the supplied SQL only into a new/empty test database. Do not import it
   over a live database without a verified backup.
7. Use folders 755 and files 644.
8. Clear browser/CDN cache and sign in.

Important
---------
The supplied source includes several historical duplicate files whose names contain

rollback workflow is removed. The active shared runtime has been upgraded globally.
