I am received the above error when attempting to load a page from a newly created tab. The VF page that controls the page include is included for the profiles experiencing the issue. The link to the page works fine for everyone, but the tab does not.
It may be caused from two tables on the page being conditional rendered by profile. When I remove the conditions, both tables load fine. Very odd.
