error when reading book in browser (config problem?)

[perler]

when I try to read a book in the browser I get things like below.

It may be a problem in the config.ini (it needs some documentation). I simply filled the db_root = line...

@perler Need more information. Are you using the Docker image? If not whats the exact command you are using to start the app?

[perler]

no it's debian 7 (kind of, actually openmediavault.org) and the command is:

cd /opt/calibre-web
python /opt/calibre-web/cps.py &

@perler Added a fix in 46c83bb. Please try again with the current HEAD.

not yet, but the error is different:

@perler Does this happen with all your books or just some? Looks like the epub file is corrupted.

[perler]

ah, good question. only with one single book and now even this book doesn't crash the reader. so you can close the issue. (but a lot of books are empty (display nothing) I will open another issue for this.
