## Oops, an error occurred! "..." is not writable. {#oops-an-error-occurred-is-not-writable}

This happens when your file permissions (Unix) are
not correct while including TypoScript from a file and trying to edit it in
the backend.

Solution: Change file permissions to make the file writeable
by the webserver, for example `chgrp www-data your/error/message/file && chmod g+w www-data`
or move the TypoScript to a location that can be written.
