I would like to add a link / image into the email template (like verify email signup) . However , when I try the following steps : 1 . Go to the amamber CP 2 . Select Setup/Configuration --> E-mail 3 . Click on any "Edit E-Mail Template" link 4 . Select the "HTML Message" option in the pop-up email template editor 5 . Click add link button in the HTML editor , there will be a pop-up for input the URL of the link When I try to input the text in the URL field , I find the input field like a read-only field and I can't input any text into it . Should I change any settings , or it is a bug ? Could anyone help ? Thanks .
