Thank you for taking the time to respond on such short notice. I’ve been using Cloudflare for nearly ten years across almost a hundred domains, and I’d definitely be lost without your help. It goes to show that you can never learn too much, no matter how simple things might seem.
I also discovered that I wasn’t actually on edge after following the instructions from this topic and to my surprise apiscp was also stuck at
HEAD detached at v3.2.45.2
Everything is working fine now—no more Internal Server Errors on the DNS Manager, and I can create sites as before.
