Hello,
Thanks for being with us, According to your page, please configure the widget width and height as follows.
width: 100%
height: 337px
You can do this at Appearance >> Widgets
Thank you for the response. I made the change you suggested, but the widget background still only covers the title of the widget and not the widget area.
See screenshot here: http://screencast.com/t/LDdQMdabA
@thetechchef did you added 337px as height? or just added 337 in height field?
You needs to add value with px so it looks like 337px
please take a look and let us know.
