Blog pages don’t show post content only headings

I’m using the Sydney theme and trying to add posts to my Blog page.
The text or photos in the post don’t show up on the Blog page, only the Post headings.
If I click on the headings I can view the posts. What is wrong?
My temporary website is wot2do.apps-1and1.com.
Thanks, Fibonacciphil

Hi,

If you use Syndey Theme, please open a new topic in Sydney Theme Forums, so we can avoid confusions, because this is another ( Alizee ) theme’s Support Forum.

Best Regards,
