slick rss in Mambo - help with variable call?

[keveen]

I have installed Slick RSS which I hoped might work with Mambo 4.6.1 here: http://the-bizness.co.uk/greenpolitics/

As you can see I get:

Fatal error: Call to undefined function: newsfeedencoding() in /home/thebizn/public_html/greenpolitics/modules/mod_slick_rss.php on line 138

the line referred to is:

$item_title = mosCommonHTML::newsfeedEncoding( $rssDoc, $item_title )

So it looks promising but I don't know enough about the code to tweak it. It works in Joomla here:

http://207.218.208.2/~thebizn/

I am hoping a coder genius will be able to spot a possible option or two to try before I give up. I'm guessing that Mambo needs a slightly different call?

Thanks
