Thank you for your rapid reply but I’m afraid my IT skills do not match up to your advice.
What does ‘remove this code from here’ mean.
Do I just delete all these referneces from the message or do i have to find where they are on the website and then delete them or what?
How do i find the ‘child theme’ ?
If this is all very basic I’m sorry but that is where I am after many years of setting up websites
