    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/qr-code-woocommerce/includes/class-woo-coupon-public-url.php:1
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/qr-code-woocommerce/includes/class-woo-bulk-qr-codes.php:3

User-side errors Passed 1 test

🔹 Test weight: 20 | This is a smoke test targeting browser errors/issues

Optimizations

Plugin configuration 93% from 29 tests

readme.txt Passed 16 tests

The readme.txt file is important because it is parsed by WordPress.org for the public listing of your plugin
3 plugin tags: qr-code, qrcode, woocommerce

qr-code-woocommerce/woocommerce-qrc.php 85% from 13 tests

The primary PHP file in "QR Code Woocommerce" version 2.0.5 is used by WordPress to initiate all plugin functionality
Please make the necessary changes and fix the following:
  • Main file name: Name the main plugin file the same as the plugin slug ("qr-code-woocommerce.php" instead of "woocommerce-qrc.php")
  • Text Domain: Since WordPress version 4.6 the text domain is optional; if specified, it must be the same as the plugin slug
