Install and configure apc on the server. Maybe APCu is installed, but needs more memory. #. Goto TYPO3 *Install Tool* --> *Configuration Presets* and choose *Database cache backend* (or: something different then `apcu`) and save. #. On a Hetzner server: Disable, save and then re-enable APC in Hetzner server management console to get it fixed.
