What may be the reason that widgets won’t display in the sidebar?
Users have to first ensure that whether the themes they are using support the widget they are wishing to add. In some cases, the problem may occur when the function.php
or file similar to that is missing. There are chances also this could happen if the user forgets to save the changes made in the widget or to refresh the older page display.
