1. Check the requirements
Confirm the required PHP version, extensions, database type and server settings before uploading the application.
2. Upload the source code
Use cPanel File Manager or FTP to upload the script to the correct document root. Extract the package and make sure the application files are in the intended directory.
3. Create the database
Create a MySQL database and database user in cPanel, then import the SQL file supplied with the script if one is included.
4. Configure the application
Update the application configuration with the correct database credentials, site URL and any required API settings. Keep credentials outside publicly accessible files where your application architecture allows it.
5. Test before launch
Open the website, test registration and login, check the admin area, test important forms and payment flows, and review the server error log for configuration problems.
