How can I notify customers that my page is down for maintenance when I am making updates to Help Center?
When you are making adjustments to your customized theme for Help Center, you can simply switch to the native Copenhagen theme. Once the native Copenhagen theme is selected, you can add text to this theme that states your site is currently down for maintenance. You will still have the ability to make adjustments to your customized theme while the native theme is active. For more information on custom themes, see Customizing your Help Center theme.
