Origami theme problems

Hi there,

My client has let me know about some display issues with the Single Category page on their EasyBlog installation:

https://www.celebrations.org.au/blog/categories/funerals

If you have a look at that page and scroll down about 4 or 5 posts, you'll see that it starts inserting each consecutive post inside the wrapper ... post dated 13 Jan is the first one it starts at.

We have a development copy of this site running and if I change the theme to anything else, the layout displays as it should:

https://updates.celebrations.org.au/blog/categories/funerals

The development site is just running the Wireframe theme.

Any ideas as to what's going on with the Origami theme?

Thanks

Nathan
