Does anyone know, please, how to fix the problem without having to redo the file Epub2 to Epub3?
Some Path? I prefer to change the content . opf file manually, if it's possible
I use caliber.
I fix all accessible metadata problem, but Daisy does not accept
my <dc: Language> en </ dc: Language>,
the error message is:
Add The Missing OPF XML: Lang Attribute
The Language Must Be Specfied (XML: Lang in OPF Package)
- also if this line is present
Thank you very much, I know you know everything ..
. :-) so maybe someone knows.
