Note: As of July 9, 2018, Blackbaud's School Management solutions (which include Core, onBoard, onCampus, onMessage, and onRecord) are utilizing a new top level navigation. This primarily affects users performing administrative tasks-constituent navigation for most parents, students, faculty, and alumni will remain the same. We appreciate your patience as we work to update our documentation. If you are seeing this message, the content of this solution is still being vetted for possible updates. Please refer to this mapping document if you need assistance finding a task in the new navigation.
When trying to access the style for a page in onMessage, you are presented with a grey box telling you the page is not found or you do not have access to the page.
Make sure that all of the page content is filled out completely. For example, if you have added a list block to the page but have not selected a list, it will throw this error when trying to view the style.
