Redirect not triggering

Check geo/device/referrer conditions in Pro rules.

Wildcard redirect mismatch

Confirm wildcard syntax uses * correctly.
Ensure source pattern actually matches the incoming path.
If preserving tail, verify target contains expected wildcard position.

CSV import issues

Use CSV with valid Source and Target headers.
Map headers correctly before import.
Review import summary for duplicate/validation reasons.

Analytics appears empty

Ensure 404 logging is enabled.
Generate test 404 traffic and refresh logs page.
Confirm server caching is not masking dynamic requests.
