I've just had a website audit, and I have two instances (so far) where there is an error on a page that doesn't exist.
For example, the error is on URL - https://www.cu-solutions.co.uk/what-we-do
I don't have any pages that are called "what we do"
Same, I have one on https://www.cu-solutions.co.uk/cart and I don't have page called "cart"
