Plex blog doesn't display new posts for days, if at all.

Why does the Plex blog ( take a long time to refresh? I’ve just got a new article in the feed that was posted 4 days ago.


From the statistics, looks like the feed has an error:
2013-12-12 06:21:48 SAX Exception (553)

I had a quick look at the source and it looks ok to me. Probably a character that hasn’t been correctly encoded.
