I have one widget_on_pages instance, being used on one page. Later, I changed the site theme. The widget_on_pages instance still shows up on the page, but under Appearance --> Widgets, the code for that widget no longer shows up.
I'd like to recover that actual widget code. Might it be in the database, and if so, where might I look?
The single instance of widgets_on_pages in Appearance --> Widgets now says only this: #1 Widgets on Pages sidebar. Use shortcode "[widgets_on_pages]"
