Pages not updating
As we scrolled down the list of troubleshooting options, there was the option to Resync your feed.
I need to access the files on my MBP and if I upgraded to i Cloud Drive I wouldn't have that option any longer, from my understanding, since Mavericks can't access i Cloud Drive. I'm unable to access ANY of my Pages, Numbers, or Keynote files from my i Cloud account on my i Mac.
Update: We no longer recommend using Feed Burner because it’s a dying product full of bugs.
Please read this article to see why you shouldn’t use Feed Burner and find out about the alternatives.
Frederick Townes, developer of this plugin, had also suggested a fix for these.
As a matter of last resort, if you have a caching plugin like W3 Total Cache or WP-Supercache installed then you may have to clear the cache from your admin panel or simply disable caching the feeds.
