Preserve attribution on direct revisit
When on (default), a later visit with empty Referer and no new ?aff=/?wm= does not clear cookies early.
Preserve attribution on direct revisit
When on, a later visit without new ?aff= / ?wm= does not clear an existing attribution cookie before it expires.
Where to find it
Admin → Settings → Affiliation → Preserve attribution on direct revisit
Setting key: aff.preserve_attribution_on_direct_revisit
Default: on
How it works
Helps when a referred user bookmarks the site and returns later to buy. A new affiliate or webmaster link still overwrites last-click attribution.
When off, a visit with empty Referer and no aff/wm params deletes both cookies. A visit that only lacks query params but still has an external Referer does not clear cookies.
