Thread:Extension talk:InputBox/ERROR : undefined method MediaWiki::getAction()

Hello to all. I just installed the extenion "InputBox-MW1.19-110961.tar.tar" and added the reference in the LocalSettings.php.

I get this error when I try to view my user-created pages : Fatal error: Call to undefined method MediaWiki::getAction in /home/thebigma/public_html/wiki/extensions/InputBox/InputBox.hooks.php on line 55"

Line 55 is : if( $wiki->getAction( $request ) !== 'edit' ){

I can however click the back arrow and view my home page or the special pages.

I commented the if statement out... /**if( $wiki->getAction( $request ) !== 'edit' ){ # not our problem return true; }*/ ...and the wiki is again functional. (Of course, I expected to see something special. Still trying to understand how to get this extension working.)
