Display full blog posts on homepage not working

Site URL: http://vardis-drivingschool.co.uk/
Hi,

I've tried setting my blog to display the full blog posts on the homepage instead of the small snippets/previews

I have also enabled this in theme settings: http://i.imgur.com/Yfdu6wW.png

but as you can see - http://vardis-drivingschool.co.uk/ no luck :slight_frown:

I did some research and I found out that you can do it manually by creating a child theme & editing the index page - and changing the_excerpt() to the_content()

I did this... (http://i.imgur.com/52PjFLj.png) but it didn't seem to make a difference.

Any idea what I can do to make this work? Thank you
