Website Preview Issue Fix & Guide

My Next.js workshop site at workshops.nicoledahlstrom.com refuses to load the preview after I follow the standard Supabase connection steps. The only message I ever see is a blank screen—no errors in the dashboard, just the preview not loading. I made a few minor tweaks to the default codebase, nothing drastic, so the fix should stay close to best-practice settings.

What I need right now is for you to:
• Connect the project to Supabase correctly, confirm the database environment variables are recognised, and make sure API calls succeed.
• Push the working build live so the public URL renders without the blank screen.
• Walk me through the exact steps you took—CLI commands, dashboard settings, and any file changes—so I can repeat the process confidently next time.

If you’ve solved similar “preview not loading” headaches before, tell me about that experience in your note and we’ll move quickly. Once the live site is stable and the hand-over guide is clear, the project is complete.
