[Plugin: WordPress SEO (possibly)]: Empty div on top of RSS feed.

Hello.

I have an empty div on the top of my RSS feed. (http://www.douglasvautour.com/feed)

It is visible with view-source in Firefox.

<div style=”display:none”>
</div>

I have disabled every plugin I can except for WordPress SEO. Also it stopped working for me after November 21st (IFTTT was able to pull data until that point), and the only thing I changed on the site was adding Google+ information into the plugin. No other plugins were added during this time.

So, my question is three-fold:

1. Can I disable WordPress SEO without losing all of my data?

2. If #1 is a no, Is there any way this plugin could be causing this problem? And if so, how can I remedy the issue?

3. If it’s not WordPress SEO, Is there any way to figure out where this div may have come from or learn how a plugin can affect the feed like this? (I can handle basic technical descriptions/understand algorithms)

I placed this on another part of the forum, before I had checked all of my other plugins, and was told to try this on a local site, but there is no way to guarantee I would be able to reduplicate the results seen on my site, so I have not done this.

EXTRA INFO

– I have an identical div in my main page source code (http://www.douglasvautour.com/) on around line 633 after the footer and before the Jetpack share buttons. However it’s an empty div..so I don’t know if it’s related.

– I had a similar problem with AddToAny Share Buttons before, so I deleted it, and the feed worked again. I thought Jetpack might have the same issue, but I disabled it and nothing changed.

Thank you very much in advance.
