Thanks, WPyogi!
I’m aware that changes will be lost. So I have kept separate files from which I can copy paste, should that happen, until I have the time to look into creating child themes. I wasn’t sure if I was gonna be able to do it myself and how time consuming it would be.
Thanks for the link!
Any advise on how I can make the above changes – whether in child theme or not – I’m assuming it would work in the same way?
