I tried to upload an ePub FixedLayout and throws me the following error:
ERROR ITMS-3000: "Line 73 column 81: character content of element "file_name" invalid; must be a string matching the regular expression "[^./: ]+([.][^./: ]+)+" at XPath /package/book/assets/asset[1]/data_file/file_name"
How I can fix it?
iBook
I'm having a similar issue.
Yes the error stopped the delivery of the book
iTunes Producer version 3.1.1
Filled everything required in iTunes Producer
Not using iBooks Author
The "MORE LIKE THIS" box on the right shows more examples of your post.
They basically list different issues.
Did the error stop the delivery of the book?
Is your iTunes Producer the current version?
Have you checked the the information you typed into iTP and filled in everything required?
Did you use iBooks Author?
