I am using Wysija Version: 188.8.131.52 with wordpress 3.8 and working fine in my website (http://184.108.40.206/Casablanca/wp/?lang=de).
There is a problem in showing subscription section when new email id is entered. The ajax is taking too much time and sometimes success message coming after 2-3 minutes. I can'tt find out why it is taking such a long time. BUt for already subscribed user it showing immediately after clicking subscribe.
Could you please take a look in the newsletter section in the right sidebar.
Thank you in advance.
