Errors on page in IE7

Hi I am new to Drupal so I am not sure if this is the right place to post this info.

I am using Drupal 6.11 and I installed and enabled ccfilter 6.x-1.3.
At this stage, when I open my website in IE 7 I get the message, 'Done, but with errors on page'.

This error doesn't occur either in Firefox 3.0 or Chrome.

The other contributed modules I have installed and enabled include:
CCK
Image
Image Assist
Messaging
Advanced Help
Advanced Help example
Path Auto
Sitemap
Token
Token Actions
Wysiwyg
Views
Views UI

As soon as I disable ccfilter, the website opens fine in IE with no error messages.
I am including a screenshot of the error message as an attachment.
