Automatic SEO Links Plugin Markup error

Hello,

I use Automatic seo links plugin

version is 1.2 but version is not important because error I write about here is on all versions and I prefer this one.

when I was checking Markup validation before, there was not any errors on home page. But after starting using this plugin, Markup Validator writes this:

http://validator.w3.org/check?uri=manutdmania.com&charset=%28detect+automatically%29&doctype=Inline&group=0

I am not such strong in PHP to make necessary changes in code, please help me if you can.

this is code:
