RSS Feed broken – help?

My RSS feed has been broken for a while. I’ve been doing troubleshooting on and off for the last month or so. If I go to genvines.com/feed, the posts *usually* show up ok. But if I go into a RSS feed reader, the posts don’t show for days and sometimes weeks. Tonight, I was testing and after disconnecting everything, the new posts are showing in 3 readers – Feedly, The Old Reader, and Digg Reader. But they are not showing in the AOL Reader and Feedreader.

I have:

1. Checked the feed with a validator, it validates fine.
2. Disabled *everything* – plugins, and even changed the plugin folder name then changed it back to make sure
3. Disabled themes – changed the name of the themes folder, and set the theme back to Twenty Twelve.

Tonight everything is still disabled. I think I’ll leave it all off overnight to see if anything goes through. But I am at my wits end. What haven’t I tried? Especially since after disabling everything, now my latest post isn’t even showing on genvines.com/feed, where most things were at least showing there before, even if there was at times a bit of a delay. What else do I need to try?

Thanks…….
