Thanks David. It was imported successfully.

Does the child theme introduce any other changes that need to be reinstated which may not be immediately obvious like the additional CSS?

If yes, what are these?

The only other one that springs to mind that is sometimes affected is the Site Logo.

Thanks David. It appears that it also affects the copyright option in the footer.

Aah yes - forgot about that :)
