How to Find & Configure Subdomain Files in (Hostinger) hPanel (After Server Migration)

If you’ve migrated your website in/to hPanel (Hostinger) and can’t access or update your subdomain (e.g., en.example.com), this guide explains where the files live and how to fix database credentials.

The Problem

After migrating, you:

• Get errors like “Error establishing a database connection” (or “Page not found” when want to access your subdomain website.

Why This Happens

When you create a subdomain via hPanel:

1. Hostinger automatically creates a new folder inside your main site’s public_html directory.
2. The folder name matches your subdomain (e.g., public_html/en/ for en.tennis-lesson.org).
3. All subdomain files (including wp-config.php, .env, or custom scripts) are stored here.
4. The subdomain does not use the main site’s database credentials by default.

Step‑by‑Step Solution

Step 1: Log into hPanel

1. Go to Hostinger’s dashboard and log in with your credentials.

Step 2: Access Your Website’s Dashboard

1. On the left‑hand menu, click Websites → Website list.
2. Find the main domain hosting your subdomain (e.g., workfromhomejobs.org).
3. Click the Dashboard button for that website.

Step 3: Create the Subdomain

1. In the website dashboard, go to the left menu → Domains → Subdomains.
2. Click Create Subdomain.
3. Fill in the details:
   • Subdomain: Enter the prefix (e.g., en for en.workfromhomejobs.org)..
4. Click Create.- Document Root: hPanel will auto‑fill: /home/u719043763/domains/workfromhomejobs.org/public_html/en).

Step 4: Verify Subdomain Settings

1. After creation, you’ll see the subdomain listed with:
   • Full subdomain name: (en.workfromhomejobs.org)
   • Directory: /home/u719043763/domains/workfromhomejobs.org/public_html/en
2. Confirm the directory path matches your expected file location.

Step 5: Create a New MySQL Database And Database User

1. Return to the Website list (left menu: Websites → Website list).
2. Click the Dashboard button for your subdomain. After that, you will see the name of main domain, but do not worry and continue.
3. Enter a  database name and database user (e.g., work_en_db). The names must be different from the main domain database name and password in your choise.
4. Click Create → Note the full database name, user name and password (e.g., u719043763_work_en_db).

You now have the 3 critical parameters:

• Database Name: u719043763_work_en_db
• Username: work_en_user
• Password: [your secure password]

Step 6: Configure Files

1. Go to File Manager in the website dashboard.
2. Navigate to:
3. /home/u719043763/domains/workfromhomejobs.org/public_html/en
4. Locate your config file:
   • WordPress: wp-config.php
   • Other CMS: .env, config/database.php, etc.
5. Edit the config file to update database credentials:

• // For WordPress (wp-config.php)
• define(‘DB_NAME’, ‘u719043763_work_en_db’);
• define(‘DB_USER’, ‘work_en_user’);
• define(‘DB_PASSWORD’, ‘your_secure_password’).

Tip: Double‑check for typos in the database name, user, and password.

 Step 7: Access phpMyAdmin

1. Go to the subdomain Databases section and click on phpMyAdmin. This opens the database management interface.
2. Import your database sql file

Step 8: Test the Subdomain

1. Clear your browser cache or use a private window.
2. Visit http://en.workfromhomejobs.org.
3. If errors occur:
   • Confirm the config file is in public_html/en/.
   • Verify database credentials match hPanel’s MySQL section.
   • Check DNS propagation (wait 1–24 hours if needed).

 

Summary

1. Create subdomain in hPanel → auto‑generates folder.
2. Create database + user → save credentials.
3. Upload database files to the new database in phpMyAdmin.
4. Go to subdomain folder public_html/en/.
5. Update config file with new database details.
6. Test subdomain after clearing cache.

By following these steps, you ensure your subdomain is fully functional on the new server.
