When I do this, I get a
403 Foridden
A potentially unsafe operation has been detected in your request to this site, and has been blocked by Wordfence.
If you are an administrator and you are certain this is a false positive, you can automatically whitelist this request and repeat the same action.
Then a checkbox asking me if I am certain this is a false positive.
Then a button that says
Whitelist This Action
Im assuming this error comes up with the updated version of WordPress, but I just dont want to click that button if its going to mess up my clients site. Can you please explain this and talk me through it. Your help would be appreciated.
Thank you
