Excerpt text won’t work?

Dear WordPressers,

First of all I want to say thanks to SimonJ that he helped me very good!
But I become to an 2nd problem, and I can’t find the solution.
http://www.web2feel.com/tribune/ <- the original
http://www.dylandamsma.com/wordpress/ <- mines ( changing colors, dont mention )

Now you may see that there isn’t any text at the mini posts and the scrollbar! Also if I add an excerpt it won’t show up.
I would be very pleased if you helped me..!

Greetings,
Dylan
