This plugin updates all URLs in the database after moving your site from one domain to another. It is useful for switching between development, testing and production stages.
Why this plugin ? WordPress stores absolute URLs in :
<ul>
<li>posts (including pages and custom post types), drafts</li>
<li>excerpts</li>
<li>medias</li>
<li>custom fields</li>
<li>options (including ‘siteurl’ and ‘home’, in wp_options table)</li>
<li>GUIDs (only for development)</li>
</ul>
When moving your website to a new domain, all these links will point to your old domain name and become outdated.
<h3>Prerequisite</h3>
Before moving the website, consider making a backup of the database. Then, once the site has been moved, you will need to manually update ‘siteurl’ in the ‘wp_options’ table, in order to access the WordPress Administration panel.

For example, hortense@example.com would only be allowed to register if example.com appeared in the domain white list. Conversely, hortense@example.com would not be allowed to register if example.com appeared in the domain black list. Anyone attempting to register using an email address outside the white list or inside te black list will receive the error message below.Anyone attempting to register using an email address outside the white list will receive an error message. Both the domain whitelist and the error message can be modified via the plugin options page (available under the Settings menu).
