How to change WordPress home and siteurl

Introduction

This article will walk you through the steps to update your home and siteurl in WordPress.

Procedure

For PHPMyAdmin:

1.  Open phpMyAdmin and click on the database associated with your WordPress installation.

2.  Look for a table named '$table-prefix_options' where '$table-prefix' represents your WordPress table prefix. This is most commonly called 'wp_options'.

3.  Locate the row labeled 'siteurl' as the 'option_name' and click on 'Edit'.

4.  In the 'option_value' box, there should be a URL present. Change this to whatever you would like the new siteurl to be. It is important to note that 'http://' or 'https://' must be present in these URLs. 'http://' will be used for sites without an SSL and 'https://' will be used for sites with an SSL, example:

Non-SSL - http://cpanel.net

SSL - https://cpanel.net

5.  Click 'go' at the bottom to submit the change.

6.  Repeat steps 3 and 4 for the row labeled 'home' as the option_name.

For inside of the Wordpress installation.

When you access your wp-admin interface for the installation, in the Settings -> General screen, there are two fields named “WordPress Address (URL)” and “Site Address (URL)”. You can modify the URL for your domain here.
