Cannot open epub

murmelbahn · 07-20-2021, 01:49 PM

Hey all,

I have bought an epub file from Weltbild.de and try to read it with Koreader. I use the latest firmware on my Kobo Forma with the latest version of Koreader.
When I try to open the epub in Koreader I only get the following error message:
ERROR: Error reading EPUB format
Cannot open document

At first I thought the download was broken and I readownloaded. Sadly this does not resolve my issue. I copied the file via OPDS to my Kobo Forma, so maybe this was the problem. When I copied the epub via USB the behavior is the same -.-.

In the next step I tried to read the epub with the default viewer from the Kobo Forma. Here I had luck. The epub is readable.

So there must be a problem with Koreader and the epub.

Attached to the post you will find a scrambled example.
Maybe one of you guys can help me with this.

There's no problem with the EPUB (besides a few font files referenced that aren't in it) and it opens fine for me. Did you try the scrambled EPUB?
