Sorry, thought that I’fd cracked it but clearly did not understand the instructions fully.
Am I correct in assuming that I simply create a new template_funtions.php file with the just the contents of the second section above (without any ?>php etc), and place this file in my child theme? If so, I think the issue is wher eI put the file. You mention that I need to uplicate the template_functions.php file in the child theme along with the root and preeceding folders. This last bit is what I think is the issue. Do you mean thatI copyall of the folders, and if so do I leave the names as lavish-pro or change them to lavish-pro-child?
