on the web site hidden link is installed WPML plugin: I received the following message from Yoast: add a "Yoast SEO Multilingual" to support WPML, as you can see in the screenshot in attachment. Consider that I'd not install a new plugin, regarding WPML, without your indications, the question of this ticket is: this plugin is necessary?
As you can see in WPML Debug info, in the web site hidden link the installed plugins are 5, the not instlled plugings are 4, as following:
WPML Multilingual CMS Installato Sì 4.2.5
WPML CMS Nav Installato Sì 1.5.0
WPML String Translation Installato Sì 2.10.3
WPML Sticky Links Non installato No n/d
WPML Translation Management Installato Sì 2.8.4
WPML Media Installato Sì 2.5.1
WooCommerce Multilingual Non installato No n/d
Gravity Forms Multilingual Installato No 1.5.0

Can you suggest a good practice?
