To start over, just discard the check-out of the page. This section explains how to accomplish that.
The option to discard a
check-out is available only when the page is in a document library that
tracks versions and requires a check-out, such as in publishing
websites. Pages that are not in such document libraries do not give you
the option, and any change you make is saved; therefore, you must
manually roll it back.
To discard the check-out of a
page, use the built-in Discard Check Out option for that page from the
library view, exactly as you would discard a check-out of a file in a
document library.
However, an easier and more accessible way to discard the check-out of
the page is through the Page ribbon. In the Page ribbon, open the
drop-down menu under the Check In button, and then select the Discard
Check Out option, as shown in Figure 1.
