If you make changes to a site published to the Internet or to a folder, you need to republish the site in order for those changes to take effect online or to be updated in the folder.
Pages in a site that have been changed, and therefore need to be republished, appear in red in the sidebar. Unchanged pages appear in blue.
Do one of the following:
If you want to change your publishing settings before republishing, select the name of the site you want to republish by clicking it in the sidebar on the left of the iWeb window.
Make your changes in the Site Publishing Settings window. You can make a public site private, or a private site public, change your contact email, and so on.
If you don’t want to change your site publishing settings, in the iWeb sidebar, simply select any page in the site that you want to republish.
Do one of the following:
To republish just the changed pages, click the Publish Site button in the toolbar at the bottom of the iWeb window.
To republish the entire site, choose File > Publish Entire Site.
When you republish, you may need to reload (refresh) pages in your browser to see your most recent changes.
