Additional info

installed @ Proxmox 6.8.12-11 as an unpriviliged lxc with this script: bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/ct/firefly.sh)"
after first account i noticed a message so ran "apt-get install -y language-pack-nl-base" and "locale-gen"
set up 2 more accounts and ran into error.

tried to do a fresh install (deleted lxc completly and reinstalled), after install ran "apt-get install -y language-pack-nl-base" and "locale-gen",
ran into this error again after just a few accounts.

tried a fresh install a third time, this time without any changes (simply ignored da locale message). Was able to get all Accounts in, but after selecting Dashboard the Error occured again

Hey, thanks for opening an issue.

A 500 is very generic. What is the error exactly?

Cheers,

Iif I'm right, the file changes. I'm pretty sure it was no php file first time. It was a fileformat I'm not used to see - which didnt convern me at all - I'm pretty new to homelab etc.

Firefly III - 500 Internal Server Error :(
Hoppla! Ein Fehler ist aufgetreten.
Leider konnte dieser Fehler nicht wiederhergestellt werden :(. Firefly III ist kaputt. Der Fehler ist:

file_put_contents(/opt/firefly/storage/framework/cache/data/3b/1b/3b1b95efebe19ec7a7e6dabc89dd9f6414466887): Failed to open stream: No such file or directory

Dieser Fehler trat in der Datei /opt/firefly/vendor/laravel/framework/src/Illuminate/Filesystem/Filesystem.php in der Zeile 204 mit dem Code 0 auf.

i tried to use the lxc shell and changed the directory to /var/www. there is no firefly file or directory nearby.

what maybe helps too, is that the error obviously only occured on Accounts. So i tried to inout an expense. after that there Was no error @ Accounts

Sorry I don't know much about proxmox. But your error message clearly states where Firefly III is installed. Perhaps that is the place to try the command? :)
