Troubleshooting
Common operational issues and concrete fix checklist.
Last updated: February 18, 2026
Why you can see "link is no longer valid"
- The short code was deleted manually or by safety checks.
- The link expired based on selected lifetime mode.
- One-time link was already used.
- The code never existed or was mistyped.
Debug checklist
- Check status in dashboard/admin list (active vs deleted).
- Test in incognito to bypass stale local session state.
- If redirect persists after deletion, verify server cache/CDN layer is purged.
Locale and redirect loop issues
- Use path-based locale URLs (`/ru/...`) instead of query locale parameters.
- Keep rewrite rules aligned in Apache or Nginx to avoid redirect loops.
- After changing rewrite rules, clear browser cache and test with hard refresh.
