After disabling some configuration settings in the blog portlet, the separator line is not after the blog entry, it is before the author and partially interferes on that text line.
STEPS TO REPRODUCE
1. start liferay
2. add a blogs page or portlet to a page
3. change the configuration of blogs portlet to uncheck "Enable Flags", "Enable Ratings", "Enable Comment Ratings" and "Enable Social Bookmarks".
3. create a new blog
Separator line is in the correct position (after the blog entry)
Separator line obscures comments and author name (see screenshot)
