Log in to your site
To move from the publicly accessible version of your site into its administrative “Back End” where you can change content, you need to log in. Many sites will have a log in link for administrators (check the footer or bottom of the sidebar), but as long as you know the log in address, you don’t need a link: just add /wp-admin at the end of your site’s regular address, like this: www.mysite.com/wp-admin, and hit return. (/login usually works too, if that’s easier).
Go back and forth between your site and its dashboard
Once you’ve logged in, you’ll be at the site’s administrative view, or control panel, and a thin black menu will appear at the top of the site window. This menu, often called the “Admin Bar,” gives you a way to get back and forth between the public site and the administrative back end so you can work on your site.
From dashboard, you can always click the name of your site (at the far left of the thin black menu) and a Visit Site link will appear so you can go to the live site itself. From the live site, you can likewise click the name and choose the “Dashboard” link that appears.
From the Dashboard, click to your site’s name to visit the public version of your site:
Or, from the public version, click to go back to the dashboard (or one of its specific sections):
Enter “Edit mode” for the post or page you are on
To edit a particular page simply to go to that page on the live site and click Edit Post (or Page) from the Admin Menu.
