Update WordPress via the Dashboard
Once you've logged into your WordPress Admin, it’s time to check for updates. When an update is available, you’ll see a notice at the top of your dashboard, shown below. Go to Dashboard > Updates or click Please update now to go to the Updates screen and begin the process.
If you don’t see the notice or the update list is empty, but you know there is a new version of WordPress available, click Check Again to refresh the list. When the update appears, click Update Now to update WordPress.
That’s it! When the process is complete, you’ll receive a welcome message letting you know that you’ve successfully upgraded WordPress. Exit this screen and take a few minutes to click through and test your site to ensure that pages are appearing correctly and that it functions as expected.
