SRP 50% 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
Please fix the following items
  • 1× GET requests to PHP files have triggered server-side errors or warnings:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function site_url() in wp-content/plugins/ajax-load-more-post/templates/index.php:1

User-side errors Passed 1 test

Optimizations

Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

The readme.txt file is undoubtedly the most important file in your plugin, preparing it for public listing on WordPress.org
These attributes need your attention:
  • Tags: Too many tags (30 tag instead of maximum 10); only the first 5 tags are used in your directory listing
The official readme.txt is a good inspiration

ajax-load-more-post/plugin.php 85% from 13 tests

The main PHP file in "Ajax Load More - WordPress infinite scroll" ver. 2.1 adds more information about the plugin and also serves as the entry point for this plugin
You should first fix the following items:
  • Main file name: Please rename the main PHP file in this plugin to the plugin slug ("ajax-load-more-post.php" instead of "plugin.php")
  • Text Domain: You no longer need to specify the text domain since WordPress 4.6; it must be the same as the plugin slug
