Originally created by @plague-doctor on GitHub (Jul 26, 2023).
After upgrade server to version 2.3.x (currently running 2.3.3, but I am not sure when it started) many audiobooks give an empty page.
Tried so far:
- re-installation of ABS app
- re-scanning of books on ABS server (including wiping current config)
No errors on the server in DEBUG logging mode.
#### Android Issue
Android version: 0.9.65-beta
Device model: OnePlus 9-PRO
Stock or customized system: LineageOS
Books are displayed correctly:

Are the books that are giving an empty page downloaded books? Is there a pattern you can identify with the ones that show and the ones that don't?

@plague-doctor commented on GitHub (Jul 26, 2023):
No, the empty page give books I try to play from the server (2.3.3 Docker).
This is a problem - I cannot figure out any pattern...
I am happy to provide one or two problematic audiobooks if it makes it easier to trouble shoot.

Both of these caused the mobile app to not load the book page. They are fixed in v2.4.4 but if you are using OPF you still have to remove those empty genres/tags.

There were 2 issues fixed related to this.
1. If you are using OPF files on your directories they may have created empty genres/tags. https://github.com/advplyr/audiobookshelf/issues/2142
2. If you are using ebooks there was a bug where the ebookFormat wasn't getting set correctly. https://github.com/advplyr/audiobookshelf/issues/2126

@plague-doctor commented on GitHub (Oct 17, 2023):
Nope. Still the same. There are some books in my library which play fine via the web gui, but they are not working at all with the app.
There is a zip with two such books (only short fragments of the audiobooks). I hope someone can take a look and help me to figure out what is going on there... audiobooks.zip

Are you using OPF files?
Do you have any ebook files with those books? Like a pdf
Are you still using an older server version v2.3.3?

Can you share a screenshot of the details tab for one of the books that is not loading in the mobile app?

That empty genre and tag have to be removed. This will most likely be a manual process for you unless you are comfortable opening the sqlite db.

Yeah you came across [#2142](https://github.com/advplyr/audiobookshelf/issues/2142)
