Hello,

I’ve restored the backup. I’ve checked this backup. This is really the first backup, before moving to the child theme. You can check it in admin panel. This backup was made before preparing to the updating. Just like before the second updating.
You may try again.
And by the way. I’ve commented my php code in functions.php
I’m not sure but maybe it will help you. If I shouldn’t do it I can fix it.
In general, good luck to you.
