Here is what Azione support wrote to me:
Your layout broke as soon as the style.css was updated to the 1.5.9 version. Additionally there is evidence your theme files were out of synch - we replaced the theme image, social links widget and "download all updates" option over a year ago, but they still exist in your previous version (you can see this if you go to Appearance > Themes and the thumbnails are different).
I can't understand what that means. Can anyone help?
