se avete qualche problema con i vostri feed rss (ad esempio quando usate lettere accentate o caratteri particolari nei vostri post) il plugin entity2ncr potrebbe esservi utile.
Entity2NCR (NCR = Numeric Character Reference) converts various HTML character entities (» & © and so on) to their numeric equivalents (» & © etc.). Many WordPress users are running afoul of character entities appearing in their comment RSS feeds, which many RSS/syndication readers fail on (also causes Firefox to get a mite testy). This should fix the problem.
