Thread:Project:Support desk/Shoutbox-Extension wont work

Hello,

I'm not entirely new to MediaWiki but I recently started my very first on my own. Now this Wiki is for students of my university to have a basis to share documents like examns or other works. To give them an easy way to communicate with each other beside the official forum, I want to provide a Shoutbox at the main page of my Wiki.

I've created an account at Shoutbox.us and followed the steps that are listed on the Extension-article:

http://www.mediawiki.org/wiki/Extension:ShoutBox

However, after adding the require-function to my LocalSettings.php, my Wiki wont work and I receive the following message:

Deprecated: Call-time pass-by-reference has been deprecated in /home/www/cwcity/hosting/b/i/hph/htdocs/extensions/ShoutBox.php on line 214

Fatal error: Call to a member function addMessage on a non-object in /home/www/cwcity/hosting/b/i/hph/htdocs/extensions/ShoutBox.php on line 77

My first thought (after checking wether I made a mistake) was that the version numbers weren't supported:

MediaWiki: 1.19.1

PHP: 5.3.15 (cgi-fcgi)

MySQL: 5.1.61-0+squeeze1-log

Since the extension is rather old, my version numbers are quite ahead of the minimum requirements of the extension.

Got any clue what might have gone wrong? Thanks, hpH
