Thank you for your help. I don’t cut and paste but I will know how to fix this issue in the future. (maybe) 😉
Ok. I am still a novice at WordPress.
This issue has only arisen today. I have made no changes to the site structure, so I am not sure what I would “undo.”
How are these errors arising? I usually post directly from WordPress itself. And how would I go about fixing them and preventing them?
