Cheers for letting me know regarding the quotes, I'll get that updated in the next release.
What exactly is the problem on this page? Are you referring to the diamond question marks appearing? If so, this isn't the plugin doing this. The plugin only outputs what it is given. In this case, the feed has HTML in it, using divs instead of paragraphs. To allow the divs to act as paragraphs they have used a div with
in it. When the feed is generated, htmlentities have been run through it turing it into
& lt;div& gt; & lt;/div& gt;(spaces added for display) which could be rendering incorrectly on output.
My suggestion would be to further format the description content before the output to the page. The only way to do this would be to use the function that the plugin is utilising in the shortcode. The plugin uses SimplePie to return results, which is part of the wordpress core files.
Hope that helps. Since feeds can be completely different from one feed to the next, its rather difficult to have the plugin allow for all scenarios, this being one of the cases where the output is slightly skewed.
