Whoo Hoooo... Ok That worked. Owncloud is now has resumed in all appearances. I am getting notices of files syncing up. Deleting the first four lines:

<?php
$CONFIG = array (
'instanceid' => 'ocro12y8044t',
);

Did the trick. The older backups did not contain these lines. Thanks for getting me through this. Thanks Nick, you the Man. It does raise a curiosity about how that could happen. If you had it with Nextcloud then there must be some common or shared code.
Thank again Nick.
