Hi,

Use this fix:

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

Did you remove it?

Anyway, run these commands:

v-delete-sys-filemanager
v-add-sys-filemanager

And now apply the fix:

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
