Post loop takes away the headline, not good.

Hello again,

The headline I use in the complete blog post on the post own page,is gone when I use the Post Loop widget to display post excerpton the Blog Page.
The headline becomes a part of the text and moves from center to the left and looses it´s heading 3 status Why?

So : there are two problems :[….] should be a “read more”link.
Headline shuld remain intact in Post Loop.

Can we solve this issues?

Thanks to you all,

Kindest regards
Linda Carlén
