I migrated from the server with rather an old installation (AFAIR last time Wallabag was updated ca. Feb-March 2023) on a freshly installed FreeBSD in jail. I ran make update, all went smoothly, but there were some warnings:

After login I immediately redirected on the main URI (https://domain.com) which displays 500: Internal Server Error:
An exception has been thrown during the rendering of a template ("Setting "export_mobi" couldn't be found.")

Since there is no links on the page, I tried to enter domain.com/new and it got me to the page with menu. I can browse settings, but any attempts to open saved articles fail.

These warning are ok.
What's weird is that you are now running on the master version (it seems).

mobi export is gone in the upcoming 2.7.0 but not yet released.
Can you tell me what version is in app/config/wallabag.yml?

Can you tell me what version is in app/config/wallabag.yml?

wallabag_core:
    version: 2.6.9

I have to add that when I tried to update via

git clone
env SYMFONY_ENV=prod composer install --no-dev -o --prefer-dist
php bin/console wallabag:install --env=prod

I cannot login due to login loop on the login page and what appears to be a lack of css loaded on the page. With make update all went smoothly and login page displayed correctly but the 550 error appeared.
