HTTP/5xx (Server Error)
508 Loop Detected
The server detected an infinite loop while processing the request.
❓ Why does this happen?
WebDAV binding loops, or cPanel/LiteSpeed resource limits (entry processes) being hit on shared hosting.
✅ How to fix it
Remove circular bindings or redirects; on shared hosting, reduce concurrent processes or upgrade the plan.

// app/api/resource/route.ts

{ error: "Loop Detected", status: 508 },
