default plugin formatting gone

Hi,

I’m experiencing problems with this plugin. It’s worked just fine for months but a few days ago, something changed…

So, it appears that the formatting for my ‘events’ page is gone – both the layout for the plugin and the layout of my page (background, images and other modules). All I’m left with is a blog-like list of my events over a white background – see link.

This is the most important page on my website as my business depends on it; I use the plugin to advertise my workshops.

Any help would be appreciated!
