This is why I test upgrades first - thank you all for posting this fix. I note that the last post was April 2010, it is now February 2011, and this has still NOT been fixed! William

1. Open the file App_Code\Chat\DnnChatCodeHelper.vb in Notepad or other text editor.
2. Find the following line (309 if you have a vb editor which shows line numbers):

Dim ctx As Web.HttpContext = Web.HttpContext.Current

3. Change it to:

Dim ctx As System.Web.HttpContext = System.Web.HttpContext.Current

4. Save the modified file and if necessary re-upload it to your remote server.

As Sebastian indicated in an earlier post in this thread, this issue with the Chat module began with the introduction of the Telerik.Web.UI components in DNN 5.3.1 and is due to a namespace conflict. You indicated that you have DNN 04.08.00. I'm wondering you have a third-party extension installed which makes use of Telerik components?

Also, note that the DNN Chat module is NOT compatible with DNN 5.5.0 and above due to other issues should you decide to upgrade the site (highly recommended due to several security issues) later.
