I am getting a clipped text message on my photo book project even though there is no text on the page. Any ideas?

Do you have any pages with text, like the cover/back page? If so put the cursor at the end of the text and use the forward Delete key to remove any invisible text to the right. I've had a couple of line Returns in a text box that gave me the text warning. You'll need to check every page.

Duplicate the project. In the duplicate copy go to that page and delete it. Add a new page and the photos for that page. See if that will clear the error message.

Have you tried running the First Aid on the library, i.e. rebuild the database and repair library permissions?
