Thread:Extension talk:WikiSEO/"Notice: Undefined index: title mode in \extensions\WikiSEO\WikiSEO.body.php on line 137"

I'm using WikiSEO 1.1.1 on MediaWiki 1.22.5. For some strange reason it throws an  line twice on the page the has  variables in the article.

It happens on a build-in skin like the Monobook as well on my custom skin. If I remove the variables int he article, the notice disappears.

Seems not to be caused by other extension, since it still appeared after I deactivated them all except WikSEO via LocalSettings.php and the notice it's still displayed.

The mediawiki is currently a local installation on xampp and was upgraded from a previous MediaWiki 1.21.5/WikiSEO (Version 1.0.1): PHP 	5.4.16 MySQL 	5.5.32
