SRP 0% from 2 tests

🔹 Tests weight: 20 | A shallow check of the single-responsibility principle; PHP files should perform no action - including output of placeholder text - and trigger no errors when accessed directly
Please fix the following items
  • 3× PHP files perform the action of outputting non-empty strings when accessed directly:
    • > /wp-content/plugins/better-chat-support/inc/functions.php
    • > /wp-content/plugins/better-chat-support/inc/class-enqueue.php
    • > /wp-content/plugins/better-chat-support/messenger-chat-support.php
  • 4× GET requests to PHP files have triggered server-side errors or warnings:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_shortcode() in wp-content/plugins/better-chat-support/view/shortcodes/custom-shortcode.php:11
    • > PHP Warning
      Use of undefined constant MCS_ALERT_MSG - assumed 'MCS_ALERT_MSG' (this will throw an Error in a future version of PHP) in wp-content/plugins/better-chat-support/inc/functions.php on line 11
    • > PHP Warning
      Use of undefined constant MCS_ALERT_MSG - assumed 'MCS_ALERT_MSG' (this will throw an Error in a future version of PHP) in wp-content/plugins/better-chat-support/inc/class-enqueue.php on line 11

🔹 Test weight: 20 | This is a smoke test targeting browser errors/issues
No browser errors were detected


Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

You should put a lot of thought into formatting readme.txt as it is used by WordPress.org to prepare the public listing of your plugin
Attributes that need to be fixed:
  • Screenshots: Please add images for these screenshots: #1 (Frontend chat bubble with form), #2 (Frontend chat bubble without form), #3 (Frontend buttons), #4 (Admin panel)
You can take inspiration from this readme.txt

better-chat-support/messenger-chat-support.php 85% from 13 tests

The main PHP file in "Better Chat Support for Messenger" ver. 1.1.5 adds more information about the plugin and also serves as the entry point for this plugin
Please make the necessary changes and fix the following:
  • Text Domain: The text domain is optional since WordPress version 4.6; if you do specify it, it must be the same as the plugin slug
  • Main file name: The principal plugin file should be the same as the plugin slug ("better-chat-support.php" instead of "messenger-chat-support.php")
