Is It Possible to Restore Accidentally Deleted Widgets?

I accidentally deleted the widgets without dragging it to the inactive widgets section.

I have a backup of all the files and the database but i have changed many things on the site other than the widgets.

Can I only restore the widgets?

You have to search the wp_options database table for option_name‘s that contains widget.

That search results in:

Using the values of your backups, you’ll then proceed to restore the option_value of the missing widgets. And also the value of the option of sidebars_widgets.

Goes without saying that backing up before doing this modifications is essential.
