Please change the old code in RelatedArticles.class.php

Html::closeElement( 'div' ) .
Html::closeElement( 'div' ) .
Html::openElement( 'div', array( 'id' => 'p-lang', 'class' => 'portal' ) ) .
Html::element( 'h3', array(), wfMessage( 'relatedarticles-title' )->text() ) .
Html::openElement( 'div', array( 'class' => 'body' ) ) .
Html::openElement( 'ul', array( 'class' => 'body' ) ) .
implode( '', $relatedArticles );

to

Html::closeElement( 'div' ) .
Html::closeElement( 'div' ) .
Html::openElement( 'div', array( 'id' => 'p-relatedarticles', 'class' => 'portal', 'role' => 'navigation' ) ) .
Html::element( 'h3', array(), wfMessage( 'relatedarticles-title' )->text() ) .
Html::openElement( 'div', array( 'class' => 'body' ) ) .
Html::openElement( 'ul' ) ) .
implode( '', $relatedArticles );

In line 3 id was changed from p-lang to p-relatedarticles because p-lang is already used. In the same line the role attribute was added.

In line 4 h3 must now noted instead of the former h5.

Next to the last line the class="body" attribute was removed. No longer necessary.
