WordPress is a great tool for building websites. But it needs to be safe. One way to make it safer is by changing the database prefix.

What is a Database Prefix?

When you install WordPress, it makes a database. This database has tables. Tables store your website data. The default prefix for these tables is “wp_”. This means all tables start with “wp_”.

Why Change the Database Prefix?

The default prefix “wp_” is known by everyone. Hackers know this too. They can use it to attack your website. Changing the prefix makes it harder for them.

Steps to Change the Database Prefix

Follow these steps to change the database prefix safely:

1. Backup Your Database

Before making changes, backup your database. This is very important. If something goes wrong, you can restore the backup.

To backup your database, you can use a plugin like “UpdraftPlus” or “BackupBuddy”. You can also use phpMyAdmin if you know how to use it.

2. Open Wp-config.php File

The wp-config.php file is in your WordPress root folder. You can access it using an FTP client or your web hosting file manager.

Find this line in the file:

$table_prefix = 'wp_';

Change ‘wp_’ to a new prefix. For example, change it to ‘newprefix_’.

$table_prefix = 'newprefix_';

Save the file after making this change.

3. Rename Database Tables

Now, you need to rename the tables in your database. You can do this using phpMyAdmin.

1. Login to your web hosting cPanel.
2. Open phpMyAdmin.
3. Select your WordPress database.
4. Find all tables starting with “wp_”.
5. Rename each table to start with your new prefix “newprefix_”.

Here is a list of some tables you might see:

• wp_posts
• wp_comments
• wp_users
• wp_options

Rename them to:

• newprefix_posts
• newprefix_comments
• newprefix_users
• newprefix_options

4. Update Options Table

After renaming the tables, you need to update the options table. This table stores important settings.

In phpMyAdmin, find the table with your new prefix, like “newprefix_options”.

Look for these rows:

• wp_user_roles

Change them to:

• newprefix_user_roles

5. Update Usermeta Table

Next, update the usermeta table. This table stores user data.

In phpMyAdmin, find the table with your new prefix, like “newprefix_usermeta”.

Look for rows starting with “wp_”.

Change them to start with your new prefix, like “newprefix_”.

For example:

• wp_capabilities
• wp_user_level

Change them to:

• newprefix_capabilities
• newprefix_user_level

6. Check Your Website

After making these changes, check your website. Make sure everything works fine. If you see any errors, restore your backup and try again.
