The file manager is not working

Hello, this is the first time I’ve encountered this, after a clean install on Ubuntu, HestiaCP opens perfectly, and all other functions work only except for the file manager, I can’t access it in any way, as soon as I go to …:8083/fm/ I get an HTTP ERROR 500, I already I tried to completely reinstall the panel 2 times, I also tried it on another hoster, it’s still the same, the installation process is standard and did not add any changes. I have already tried changing the php version of the admin panel itself, as well as no changes, I tried 8.2;8.3;8.4

I see this error in the logs:

2026/03/27 08:00:22 [error] 54599#0: *6 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Class Filegator\Services\Session\Adapters\SessionStorage contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Filegator\Services\Session\SessionStorageInterface::migrate) in /usr/local/hestia/web/fm/backend/Services/Session/Adapters/SessionStorage.php on line 18" while reading response header from upstream, client: 166.1.250.37, server: _, request: "GET /fm/ HTTP/2.0", upstream: "fastcgi://unix:/run/hestia-php.sock:", host: "******.**:8083"

Hi,

Use this fix (as root):

cd /usr/local/hestia/web/fm/backend/Services/Session/Adapters/
mv SessionStorage.php SessionStorage.php.ori
curl -fsSLm20 https://raw.githubusercontent.com/hestiacp/hestiacp/refs/heads/main/install/deb/filemanager/filegator/backend/Services/Session/Adapters/SessionStorage.php -o SessionStorage.php
