Only Can see 10 posts?

Hi Everyone,

Love the Spun theme and very easy to use (www.sail-lbs.com).

I am having a slight issue in that if I publish more than 10 circle posts – only 10 will show – even though it says 11 (for example) have been published.

Any ideas? I have seen other spun sites where loads are on the Home page so it must be possible.

https://www.sail-lbs.com is the site.

Thanks in advance
