One page, three tabs
Open Pages & Posts in the Website group. The tabs across the top are Pages, Posts, and Media. Each tab is the same page it was as a separate sidebar item, at the same address, so saved links still work. Posts and Media show a lock on plans that do not include them.
Pages (/dashboard/pages): your standard template pages and blank pages, with their status. New page is the main action. See Create a page from a standard template.
Posts (/dashboard/posts): blog posts, categories, and tags. New post is the main action, and Blog settings stays in the tab's header. See Publish a blog post.
Media (/dashboard/media): the Media Library of images, documents, and downloads used across your site. See Use the Media Library for site assets.
Where the homepage and theme live
The homepage layout, words and photos, logo, and colors are edited in Website Editor, also in the Website group, not in Pages & Posts. See Use the Website Editor.
On a phone
New page or New post floats at the bottom right. Each row's Edit, View, and Delete actions sit in a ⋮ menu at the top right of the row, and the title itself opens the editor.
Common problems
Pages, Posts, or Media is missing from the sidebar. They are tabs of Pages & Posts.
The Posts or Media tab is locked. Blog posts and the Media Library are Pro; see Upgrade for a specific feature.
A page is in the list but not on the site. Check its status; drafts and archived pages are hidden from customers.
