 * My original html tag looks like this in the code:
    <html <?php language_attributes();?
   >> it outputs the next line: <html lang=”hu-HU”> after the seo plugin it outputs
   this: <html lang=**“hu-HU”xmlns=”**[http://www.w3.org/1999/xhtml&#8221](http://www.w3.org/1999/xhtml&#8221);
   xmlns:og=”[http://ogp.me/ns#&#8221](http://ogp.me/ns#&#8221); xmlns:fb=”[http://www.facebook.com/2008/fbml”&gt](http://www.facebook.com/2008/fbml”&gt);
 * There’s a missing space!!

 * katazina,
 * It should be, I explicitly added a space there; you can check this by looking
   in the aioseop_opengraph.php file at line 282, it should look exactly like this:
 *     ```
       return $output . ' xmlns="http://www.w3.org/1999/xhtml"
       ```

 * Thanks, now it works good.
    When I wrote, then it was the version 2.1.1, in version
   2.1.2 it’s ok.
