+## 6. Troubleshooting
+
+### "Readonly Database" Error
+If you see an error like `Invalid prisma.userProfile.upsert() invocation: attempt to write a readonly database`:
+
+1. **Verify Permissions:** Run the diagnostic script inside your container:
+   ```bash
+   docker exec -it node-apps node /usr/src/app/gymflow/server/check_db_perms.js
+   ```
+2. **Fix Permissions:** If the checks fail, run these commands on your NAS inside the `gymflow/server` directory:
+   ```bash
+   sudo chmod 777 .
+   sudo chmod 666 prod.db
+   ```
+   *Note: SQLite needs write access to the directory itself to create temporary journaling files (`-wal`, `-shm`).*
+
+3. **Check Docker User:** Alternatively, ensure your Docker container is running as a user who owns these files (e.g., set `user: "1000:1000"` in `docker-compose.yml` if your NAS user has that ID).
+
+### "Invalid ELF Header" Error
+If you see an error like `invalid ELF header` for `better-sqlite3.node`:
+This happens because the `node_modules` contains Windows binaries (from your local machine) instead of Linux binaries.
+
+1. **Fix Inside Container:** Run the following command to force a rebuild of native modules for Linux:
+   ```bash
+   docker exec -it node-apps /bin/sh -c "cd /usr/src/app/gymflow/server && npm rebuild better-sqlite3"
+   ```
+2. **Restart Container:** After rebuilding, restart the container:
+   ```bash
+   docker-compose restart nodejs-apps
+   ```
