Hello. If I send a newsletter with a link or blog posts, when I click on them, a url appears that does not work, for example domain.com/?nltr=MTk5OzA7aHR0cHM6Ly9pc290ZXEuaHUvYnVkYXBlc3QteGkta2VydWxldC0zLzs7MDEwNDkwYjhlNDhlY2Y3ODA4YzNkMzQ4MGYw MjE2OTU%3D
I have tried deactivating tracking and modifying the hosting’s php but nothing works. I have also done downgrades.
Thank you in advance,
Angel
