Validation Error - ..resource is reachable...
When I validate my ebook I get the result:
Message: This resource is reachable but not present in the OPF <manifest>. "Reachable" means that a reference of some kind that points to this resource exists in the epub.
I'm new at this and I'm afraid this does not make sense so I don't know where to start in fixing this problem.
Any pointers would be appreciated..
