Well that's odd. But doing a view source on those two pages shows that the P tags really are there in both cases. Its just that they look different. Using webdeveloper toolbar one can see that there are a bunch more divs for the aggregator page than the permalink page, so that is (I suspect) where the issue lies. Not that I can figure out a solution mind you - just that I can see that it isn't in the plugins not doing their thing. That leaves you with style sheet issues to address.

There are also some xhtml errors on both pages, so that *might* be related. But I'm guessing it has something to do with how the style sheets are responding to the multiple and different divs between multi and single post pages.

Thanks. I did clean up the css and html now.

HTML validates now.

That said - I still had the issue. So I had a closer look at my style.css and found my mistake (Duh! and DOH!!)

#featuredrows p
{
margin:.1em;
padding:0;
}

my bad. User Error. Thanks for helping.
