styling issue

I have installed this plugin on http://suffolkholidaylodge.co.uk/

it looks to have great potential.

I selected a layout in the options with ‘image’ and text but this didn’t appear. i think it was the ‘light’ scheme.

i also wondered whether colours etc could be amended via css.

thanks.
