Describe the bug and copy the error message

When I use the plugin, there isn't any error message showed up. But when I send the modified file to Kindle through the website, it says the document couldn't be delivered. Even when I try with the cable, it doesn't show up in my Kindle. The original .epub file still works, though.

Plugin settings and reproduce steps

1. Click on WordDumb Button
