Upgrading your WordPress installation to the latest version couldn’t be more simple since WordPress 2.7+. As with any changes to your website files, please take a backup of your account and databases before proceeding in case you need to restore your account files and databases from a backup.
How to Upgrade a WordPress Installation
- You need to first login to your WordPress admin area
- Then in the top left corner, under Dashboard, click Updates
- On the next page it will let you know if you have the latest version, if you do you will see:
- If not, you will have an Update Now button, simply click the button and you will be updated to the most up to date and secure WordPress version!
How to Enable Automatic Updates
If you’d rather enable automatic updates and not have to manually update, this can be done easily by updating the wp-config.php file in your home directory.
- Open the wp-config.php file, scroll to the bottom and append the following to allow auto-updating of the WP core installation:
define( 'WP_AUTO_UPDATE_CORE', true );
- You can also enable auto-updates for your plugins and themes as follows, also via the wp-config.php file:
add_filter( 'auto_update_plugin', '__return_true' );
add_filter( 'auto_update_theme', '__return_true' );
