Warning page

If your publication has some pages locked you should have a warning page to be displayed when a locked page is requested by a user, to tell the user why the requested page cannot be shown and could also offer a link to your website for registering and so unlocking the publication.

You can use the Page Wizard to generate a Warning page for you and modify it to suit your needs afterwards.

The Warning message page can be defined in Files Tab in Publication Window, by selecting the desired file and using the drop-down menu made available when you right-click on the file.
Select Set/Unset as Warning message for locked pages. Then, if the publication isn't registered when a locked page is requested, your Warning page will be shown.

You can also set your Warning page in the Protection Tab.
