Thread:Project:Support desk/Force IE10 to use Document Mode IE8/reply (7)

I resolved this issue.

in outputpage.php I changed the methodː

public function getHeadLinksArray( $addContentType = false )

i changed

if ( $wgHtml5 ) { $tags['meta-charset'] = Html::element( 'meta', array( 'charset' => 'UTF-8' ) ); );

to

if ( $wgHtml5 ) { $tags['meta-charset'] = Html::element( 'meta', array( 'charset' => 'UTF-8' ) ); $tags['meta-http-equiv'] = Html::element( 'meta', array( 'http-equiv' => 'X-UA-Compatible' ,'content' => 'IE=EmulateIE8' ) );

works perfect :D
