Describe the Bug

When I export the books in PDF with the API, all the pages al empty.
All the other exports (markdown, HTML, plaintext) works

Steps to Reproduce

execute the API with the URL http://bookstack:6875/api/books/17/export/pdf
a PDF with all the pages white is received

Expected Behaviour

A PDF with the book is downloaded.

Screenshots or Additional Context

In the docker logs when Bookstack starts I see that the version is the latest:

Linuxserver.io version: v24.05.2-ls152
Build-date: 2024-07-01T18:27:53+00:00

But in the UI I see v22.11.1, do you know why?

Browser Details

No response

Exact BookStack Version

v24.05.2-ls152

That's odd, If you click the profile menu in the header do you see "My account" or do you see "Edit Profile" (or similar)?

Otherwise, does the export work okay in the application if you export the book as PDF? IF not, what about the page?
If you go directly to http://bookstack:6875/api/books/17/export/pdf in the browser as a user with API pemission, does the browser download a book export okay?

I see "Edit Profile"

This works, the PDFs are ok

* If you go directly to `http://bookstack:6875/api/books/17/export/pdf` in the browser as a user with API pemission, does the browser download a book export okay?

Even in this way it works. That's so strange.......

Damn, damn, damn! It's another problem not related to BookStack.
As soon as the PDFs are created I upload them to DropBox with the APIs. The problem lies there because I've just checked the local temp files and they are ok.
I'm sorry!

I still have the problem about the version. Am I using the latest or am I stuck at V22?

Sounds like you're currently stuck at v22.11.1.
Are you sure you're not accidentally running multiple containers at one? (old and new).
