Server Error

Sorry, something went terribly wrong!

E_ERROR - Call to undefined method Grav\Common\Utils::arrayFlatten()

For further details please review your logs/ folder, or enable displaying of errors in your system configuration.

Is this a fresh install? Ideally you would set errors.display to true in your system.yaml file and get the more detailed error information. It’s hard to help without having more context for the error.

Thanks for your help!
Its working now.

Kind regards,
