You need to upload the "ajaxWDwx-settings.js" file to your server as you've included it in your "top.php". It's not there at the moment. You need to make all the changes in this file.
I’ve just done.
I’ve set like this “var wxIconSet = wxIconSet1” but i’ve all images in “ajax-images/”.
Unfortunately, there isn’t any choise for that.
Do you believe that i come back to the previously version?
Best regards,
Alessandro
