Using Confluence 4.2.12.
I have an excerpt that I include on a page that is viewable by two groups, X & Y. However, via permissions I have restricted viewing of the excerpt to group X. I notice when group Y tries to view the page containing the excerpt, instead of simply suppressing the excerpt, the following message is displayed (image attached):
The page [page name] does not exist.

Is there any way to suppress this message? Or is there a better approach to 'hiding' content based on group permissions?
