wp_localize_script no longer working after 5.5 update
I just had this issue myself and was able to fix it by assigning it to the script that required the data and not to “jquery”, example below: wp_localize_script(‘jquery’, ‘vars’, $vars); wp_localize_script( ‘replace-with-your-script-name’, ‘vars’, $vars); To clarify: This would be the same name that was used to identify in wp_enqueue_script() and should match it.
