Front page styling gone?

Hi I have been using your theme Simplicity and I recently noised that the styling for the FrontPage suddenly disappears. I have had it working and didn´t really pay much attention to it, just made sure that the installation was up to date. And now the header widget is not styled? It just looks boring. I just uploaded the latest theme to my themes folder and just changed logo and background image... besides that I havent changed anything and it still looks like the css is not being used for some reason, anyone have any idea what can be the issue?

You can look at the header here:

Hi,

Did you change something with body classess? You don't have imageBg class in your body element.

I just updated a fresh copy of the theme, so it should be untouched, except I updated some image files...
Do you know what specifically is missing so I can search for it and see ? I deactivated all my plugins so it should not be interfering with anything.

Ok, so did you update your theme, right? and after updating you have this issue? Colud you send me a PM with FTP access? I'll check files or you can compare your theme files with files from the latest version of the theme (check exactly gavern/hooks.php file and gavern/helpers/helpers.layout.php file)
