That’s great to hear.
A temporary get around for me was doing this:
<?php echo str_replace('&", "&", do_shortcode('[wp-rss-aggregator]')); ?>
Basically For some reason ampersands are getting encoded which prevented any HTML entities from working, so we just swap them out.
EDIT: This editor isn’t showing correctly, the first & should have a semi colon after it.
I’m getting a similar thing: https://www.dropbox.com/s/6f3astl8senr0uk/Screenshot%202014-06-24%2013.08.54.jpg
The feeds are from the BBC and Fifa: http://feeds.bbci.co.uk/news/world/rss.xml and http://www.fifa.com/rss/index.xml.
Be great to find a way to solve this. Cheers!
EDIT: I’m using latest versions of everything.
