website has a bug

The WordPress function wp_localize_script() is used for making translated strings available to the Javascript side of things.

The notice you are seeing is due to one of your plugins using wp_localize_script(), and passing in a non-array as the third parameter.

Are you using a “single sign on” plugin? If so, see if temporarily disabling this makes the notice go away. If so, that is the source of the issue.
