Extension talk:Dynamic Article List for PHP4

Page wont refresh
I just setup "Dynamic Article List for PHP4" as an extension for my MediaWiki setup, and I copied the code from the homepage of checkmate security group for The newly posted articles, new blog articles, most popular articles, etc.

My issue is that it doesnt update with every refresh of the page. Only when I edit and save the page does all of the new information update.

It doesn't look like this issue has been solved, but it is happening to other people[1]

PHP Error at the top of the page.
I'm using the extension at http://www.st-george-squadron.co.uk and it works. But I get the following error message:

Undefined variable: r in /home/stgeo/public_html/sgs/wiki/extensions/DynamicArticleList.php on line 275
