"Last updated by" text showing up in header

Here’s an example of what I’m experiencing:

http://www.phacient.com/category/technology/

I’ve noticed that when I go to tag or category archives, I am now seeing some text in the header that says:

Last updated by [user] at [date] along the top left.

I’ve found an extra <p> line inserted in that area with a class labeled “updated”. When I remove it from the source code (temporarily) everything goes back to normal. Here it is.

<p class=”updated” itemscope=”” itemtype=”http://schema.org/WebPage&#8221; itemid=”http://www.phacient.com/2012/02/how-can-social-media-help-internal-collaboration/”>Last updated by <span style=”float:none” class=”author vcard”><span class=”fn”>Patrick Healy</span></span> at <time itemprop=”dateModified” datetime=”2012-02-10T11:50:18+00:00″>February 10, 2012</time>.</p>

When I search this code I get a result that it’s in this plugin:

http://plugins.svn.wordpress.org/authorsure/trunk/authorsure.php

I’m OK getting rid of it altogether if need be but I don’t want to have to worry about doing it every time the plugin updates. I’m sure it’s supposed to be at the bottom of the page.

I’ve tried everything I could think of in terms of the plugin settings. Any ideas?

Thanks in advance for the help.
