Welcome to the forum.
Do you mean as inthe thread below which is just a few down from your post.

See www.grainge.org for RoboHelp and Authoring tips
Yes, this post does look similar to what I'm seeing in Firefox. Just to be sure, your solution would be to regenerate the help to a new folder after deleting the CPD file, with RoboHelp closed?
Thanks for your help. It appears that there was a new filter that was installed during a server upgrade that prevented the files from properly displaying. In theory, it has fixed our issue.
