If you’d like to unpublish your full website without completely deleting it, you can update the privacy settings in your WordPress admin panel. Once you’re in the admin area, choose “Settings” from the left side of the screen. In the pop-up menu, choose “Reading.” Scroll down on the page until you see the section listed as “Site Visibility” and use the radio buttons to select your desired visibility.
To update the settings so only you can see the site, choose “visible only to administrators of your site.” Once you’re ready to publish your site again, use either “Public and allow search engines to index this site” or “Public but discourage search engines from index[ing] this site.”
Once you’ve finished, scroll down to the bottom of the screen and choose “save changes.”
