The Version Info plugin helps you track essential version information for your WordPress install by displaying key system details such as WordPress version, PHP version, Web Server type, and MySQL version. This can be displayed in three areas:
<ul>
<li>Admin footer – Displays WordPress, PHP, MySQL, and Web Server versions in the footer for quick reference.</li>
<li>WP-Admin Bar – Optionally add version details to the top WP-Admin bar for instant visibility while navigating the admin area.</li>
<li>Dashboard Widget – Activate the dashboard widget via the Screen Options to quickly view your site’s version information.</li>
</ul>
Key features of this plugin include:
<ul>
<li>Shows the current WordPress version. If a new version is available, it will display the current version alongside the latest available version in the footer, with a link to update.</li>
<li>Displays the PHP version running on your server, making it easy to verify if your site meets compatibility requirements for plugins and themes.</li>
<li>Shows the Web Server type and version, whether you’re using Apache, Nginx, or another server setup.</li>
<li>Includes the MySQL version to help you track the database version your WordPress site uses.</li>
</ul>
