Hi. I've created an epub using Indesign CS5.5. The epub validates correctly. I have tried uploading it to iBooks with iTunes producer. And I am receiving these error messages for each html page:
ERROR ITMS-9000: "Filename.epub: Invalid URL in Nav file My book 05 21st Oct 2012-1.html#toc_marker-1 : Illegal character in path at index 3: HTG_iPad_Mini_05_21st_Oct_2012-1.html#toc_marker-1" at Book (applepackagename)
Now I found a blog post on Pigs, Gourds & Wikis
which explains the error is because iBooks doesn't allow spaces in file names.
So I opened the toc.ncx file in Notepad +. I change all the file names, like the one listed above, so all the blank spaces I changed to underscores_ .
However when I tried to reupload the file I'm still getting errors. I thought I'd finished but I haven't. Please, any ideas how I can fix this?
