Login to your Glow account.
Once logged in, click on Clients from the main left hand menu.
The Clients screen will load the Live clients tab from the inner menu automatically. Click on the name of the client for whom you want to update the WordPress version.
You will now be shown the client area. The client’s name that you clicked in Step 3 above will be shown as the main heading at the top and the inner menu will load on the WordPress tab by default.
If an update is available, you will see it represented as so:
5.6 –> 5.6.1
This indicates that an update is required from version 5.6 to version 5.6.1.
To perform the update, begin by clicking on the checkbox to the left of the version number.
Having clicked on the checkbox you will notice that the Wait and Update buttons in the bottom right corner are now clickable.
Click on the Update button.
Glow will begin the update process. The information bar will flash subtly as the update is in progress and once it’s complete, you will see a note that says Up to date.
