I am working on a Magento 2.1.2 project, theme Porto. I installed the MageMonkey extension for Mailchimp integration.
I strugle with displaying the messages of successful / unsuccessful subscription to newsletter on the homepage. On local, everything works as intended but on preprod server the
afterRenderResult() method of
Magento\Theme\Controller\Result\MessagePlugin is not called, so no
mage-messages cookie is set.
On preprod if I visit another page, the messages are displayed.
Has anyone had this problem ?
I even have deployed a preprod database on local thinking that the problem is in the database.
Maybe it is a caching problem ?
