Saving Drafts of Pages in WordPress Without Updating the Live Page

Log in to wp-admin with user name and password.
In the dashboard, go to “Pages” and click on the published page you want to make a draft of.
On the right-hand side, there will be a box called “Drafts of Revisions” and click “Save a Draft” (this creates a draft copy you can edit).
Make the changes you want to the draft page you created.
To the right, under “Publish” click “Save Draft”.
If you revisit this later on you will need to log back in wp-admin with user and password.
In the dashboard, click “Pages”.
Click on the page you created the draft for (NOTE: There is no secondary file you go back to the same page you created the draft in.)
To the right, you will notice a link to the draft page just above save a draft.
Click on the draft link.
Once the page is ready you can click “Publish”.
