@Bhavika Khatri thanks for your advice but adding ?test123 to the address still gives me the ‘are you human?’ page and doesn’t take me to the site.
I didn’t set the website up so I don’t know about a cloudflare firewall or how to check the settings – and I can’t log into the website to check what plug ins there are as I can’t get past this screen. The person that set the original site up is no longer contactable.
