Epub Validation Failed

  1. 3 years ago

    I am new to pubcoder. We have an ebook with artwork, so the images I used were high quality since I found that pubcoder reduces the images to the appropriate size for the output.

    I have read aloud audio files that all seem to work fine.

    I have inserted 3 videos, but they are mp4's not from youtube.

    I consolidated everything.

    I cannot figure out why pubcoder says "Epub Validation Failed" Is there a way to get more information as to WHY it failed?

    It is a pretty big file because of the images.

    Hello Hollis,
    it's not the pubcoder file that fails to validate, it's the epubcheck program on its own that fails to execute because of a Java incompatibility. Please install JDK 7 or later.
