Hello,
Such issue is usually caused by incorrect settings of the blog section. Please take a look at the Corporate Site sample site which can be installed with standard installation of Kentico
CMS:
http://devnet.kentico.com/docs/devguide/website_template.htm. Please compare the settings in there with yours.
If you are still unable to determine where the catch is, please provide us with some screenshots and detailed description of how you've setup your repeaters and how their transformations look like.
Best regards
Ondrej Vasil
