Hi everyone. I have a problem, until what day ago, who signed up for the newsletter by clicking on the “subscribe” button, was redirected to a “basic” page with the words “thank you for registering” … the page I wanted to change it , but not having time I had left it. Now unfortunately it does not appear anymore, you click on the button, you are registered for the newsletter, but the page remains blank, for a few minutes and then Error 500 … does not find the page .. what happened? where do i find this page? this link? how do i edit it?
