Some WordPress themes allow site managers to configure/manage common elements through a dashboard interface rather than individual widgets. Consult your web-development team to determine whether any of these custom settings apply.
The two most common places for these settings are:
- Appearance > Customize
- Appearance > Theme Options
NOTE: while similar options and settings may appear in each of these screens, they may not be one-in-the-same, and may not actually impact anything on the site.
An example of the "Customize" panel of options is shown below.
