It looks like a bug in the latest FileGator release (7.13.4).

SessionStorage missing migrate() method after #576 - causes Fatal Error

opened 08:19PM - 04 Mar 26 UTC

## Bug After PR #576 ("regenerate/migrate session on log in"), the `SessionStor…ageInterface` now requires a `migrate()` method: https://github.com/filegator/filegator/blob/master/backend/Services/Session/SessionStorageInterface.php#L18 But the `SessionStorage` adapter does not implement it: https://github.com/filegator/filegator/blob/master/backend/Services/Session/Adapters/SessionStorage.php This causes a PHP Fatal Error when opening FileGator: 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 SessionStorage.php on line 18 ## How to reproduce 1. Fresh install of FileGator v7.13.4 (or Hestia CP 1.9.4 which bundles it) 2. Open the file manager → 500 Internal Server Error ## Fix Add the missing method to `SessionStorage.php`: ```php public function migrate($destroy = false, $lifetime = null): bool { if ($this->getSession() && $this->getSession()->isStarted()) { return $this->getSession()->migrate($destroy, $lifetime); } return false; }

The user who raised the issue provided a fix. I’ve added the fix to the PHP file so you can apply it easily.

sudo -i
cd /usr/local/hestia/web/fm/backend/Services/Session/Adapters/
mv SessionStorage.php SessionStorage.php.ori
