Rss network not showing

Hi,

I'm using the edu-clean theme.
I've installed the latest posts and post indexer plugin, added the specified line in htaccess, but the latest posts are not showing on the homepage.
I've also configured the rss options in edu theme settings (the 1st block displays well; it's my main rss, but the 2nd and 3rd block, which are the latest posts and comments, do not).

Help,pls!
Thx,

Darja
