 * Our logs are filled with PHP notices that have been tracked down to incorrect
   usage of `wp_localize_script` – specifically in one or more of the localization
   calls from `handl_utm_grabber_enqueue` in **handl-utm-grabber-v3.php.** Can you
   please track down the issue and provide a fix?
   PHP Notice: Function WP_Scripts::
   localize was called **incorrectly**. The `$l10n` parameter must be an array. 
   To pass arbitrary data to scripts, use the `wp_add_inline_script()` function 
   instead.
