I believe my Edge certificate was configured incorrectly on my website, so I wanted to disable it and generate a new one. But it looks like Cloudflare is only give me the option to either order an Advanced Certificate or to upload a custom certificate. Is it not possible to generate a new Edge Certificate after disabling it?
Sorry I made a mistake. I confused the Edge Certificare for the Origin Certificate. I generated a new Origin Certificate and now my issue has resolved! (For now at least)
