Plug-in stops working when I remove cufon-yui.js

Hi, I'm using a slide-plugin that is called Recent Posts Slider.
It worked perfectly until i wanted to remove the cufon-fonts that Dzonia theme uses.
Here is the site I'm working on: http://samfast.com/redesign/

I have placed this line on my front page:
<?php if (function_exists('rps_show')) echo rps_show(); ?>

Everything workes fine, but when I try to remove the file called cufon-yui.js the plugin stops displaying my posts. I've also tried to comment this line out from funtions.php:
wp_enqueue_script( 'inkthemes-confu-ui', get_template_directory_uri()."/js/cufon-yui.js", array('jquery'));

and when I do the plugin stops working again.

I can't figure out how the plugin could be dependent on the cufon-yui-file and how i go about removing cufon without the plugin being affected.

The error messages I get are:
Notice: Undefined index: 0 in /www/webvol9/g0/7ou0qbxr50pzpj5/samfast.com/public_html/redesign/wp-content/plugins/recent-posts-slider/recent-posts-slider.php on line 502

Notice: register_widget_control is not used since version 2.8! Use wp_register_widget_control() instead. in /www/webvol9/g0/7ou0qbxr50pzpj5/samfast.com/public_html/redesign/wp-includes/functions.php on line 2919

Help would be greatly appreciated!

 

Hello,

Undo your old customization.
and for removing the cufon, go to js > custom.js present in your theme directory and remove the code given below

Code:

 //Cufon Replacement in heading
  jQuery(document).ready(function() {
//Cufon.replace('h1')('h2')('h3')('h4')('h5')('h6');
Cufon.replace('h1, h2, h3, h4, h5, h6,.content .post .date li', { fontFamily: 'MankSans-Medium', hover: true });
});

This will solve your issue.

 

Thank you for the sollution!
Now the font is gone and the plugin still works =)
