Due to security reasons if have protected my /administrator directory with user & password via a .htaccess located in /administrator. However if I want to view online newsletters either from the frontend newsletter or by clicking on the link in the mail {readonline} I have to key in the user and passwort in the popup window as well. I can also just "cancel" and I can see the newsletter online, too. If I delete the .htaccess everything works fine.
Could you please tell how to avoid the popup and to avoid key in the user and passwort?
