Description: Controls whether QR codes are available in the Share modal and which provider is used.
How it works: When enabled, QR image URLs are generated for the short link and shown in the Share UI; you can disable to avoid external QR endpoints.
How to access / enable: WP Admin → AegisLink → ShortURL Links → Settings → QR Provider.
Recommended setting: Use QRServer for quick QR support; set to Disabled if you want zero external QR requests.
