The following issues need your attention
  • 3× GET requests to PHP files trigger server-side errors or Error 500 responses:
    • > PHP Warning
      Use of undefined constant ABSPATH - assumed 'ABSPATH' (this will throw an Error in a future version of PHP) in wp-content/plugins/affiliates-referrals-for-woocommerce/includes/index.php on line 4
    • > PHP Fatal error
      require_once(): Failed opening required 'ABSPATHwp-includes/pluggable.php' (include_path='.:/usr/share/php') in wp-content/plugins/affiliates-referrals-for-woocommerce/includes/index.php on line 4
    • > PHP Warning
      require_once(ABSPATHwp-includes/pluggable.php): failed to open stream: No such file or directory in wp-content/plugins/affiliates-referrals-for-woocommerce/includes/index.php on line 4

User-side errors Passed 1 test

🔹 Test weight: 20 | Just a short smoke test targeting errors on the browser (console and network errors and warnings)

Plugin configuration 86% from 29 tests

readme.txt 81% from 16 tests

Don't ignore readme.txt as it is the file that instructs WordPress.org on how to present your plugin to the world
Attributes that require attention:
  • Tags: There are too many tags (22 tag instead of maximum 10)
  • Plugin Name: You should set the name of your plugin on the first line ( === affiliates-referrals-for-woocommerce === )
  • Donate link: Please fix this invalid URI: ""
The official readme.txt is a good inspiration

affiliates-referrals-for-woocommerce/index.php 92% from 13 tests

"Affiliates Referral for WC" version 1.0.0's primary PHP file adds more information about the plugin and serves as the entry point for WordPress
Please make the necessary changes and fix the following:
  • Main file name: It is recommended to name the main PHP file as the plugin slug ("affiliates-referrals-for-woocommerce.php" instead of "index.php")
