Since a while users get redirected to a specific page after login. The POST request that contains the user credentials returns a Location: /script-blocks/newsletter redirection in the HTTP header. I don't have a glue, where this redirection comes from and why it points to exactly this page. Another strange thing is, that users are only sometimes redirected to that page. I can't find out why this happens. Does somebody have any idea?
