Everything seems fine, however this is by no means an exhaustive test

SRP 0% from 2 tests

🔹 Tests weight: 20 | It is important to ensure that your PHP files perform no action when accessed directly, respecting the single-responsibility principle
The following issues need your attention
  • 2× PHP files perform the task of outputting text when accessed with GET requests:
    • > /wp-content/plugins/cleanup-duplicate-meta/class-plugin.php
    • > /wp-content/plugins/cleanup-duplicate-meta/plugin.php
  • 10× PHP files trigger server errors when accessed directly:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function __() in wp-content/plugins/cleanup-duplicate-meta/lib/config/postmeta.php:17

User-side errors Passed 1 test

🔹 Test weight: 20 | A shallow check that no browser errors were triggered
No browser errors were detected


Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

Often overlooked, readme.txt is one of the most important files in your plugin
These attributes need your attention:
  • Screenshots: These screenshots require images: #1 (The plugin's page in Tools > 'Cleanup Duplicates'.), #2 (Screen for both the Post Meta and User Meta controls.), #3 (An example of the table generated when clicking on 'Check for Duplicates' button. The results are sorted by meta key.), #4 (After clicking on the 'Count Duplicates' button, notification is displayed of the number of duplicates found (which could be deleted).), #5 (The message after clicking on 'Cleanup Post Meta'.)
The official readme.txt might help

cleanup-duplicate-meta/plugin.php 85% from 13 tests

The main PHP script in "Cleanup Duplicate Meta" version 1.0.2 is automatically included on every request by WordPress
Please take the time to fix the following:
  • Main file name: The principal plugin file should be the same as the plugin slug ("cleanup-duplicate-meta.php" instead of "plugin.php")
  • Text Domain: The text domain name should consist of only dashes and lowercase characters
