Almost there! Just fix the following items
  • 1× PHP files trigger errors when accessed directly with GET requests:
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/contact-form-7-charts/cf7charts.php:27

User-side errors Passed 1 test

🔹 Test weight: 20 | This is a shallow check for browser errors
Everything seems fine, but this is not an exhaustive test


Plugin configuration 86% 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
Attributes that require attention:
  • Screenshots: These screenshots have no corresponding images in /assets: #1 (Admin dashboard widget showing six-month and one-month (daily) trend charts of Contact Form 7 activity by form, similar to Google Analytics trendcharts.), #2 (Admin dashboard widget showing the one-month pie chart of combined Contact Form 7 activity by form.)
Please take inspiration from this readme.txt

contact-form-7-charts/cf7charts.php 77% from 13 tests

The entry point to "Contact Form 7 Charts" version 1.0 8/1/13... is a PHP file that has certain tags in its header comment area

  • Main file name: The principal plugin file should be the same as the plugin slug ("contact-form-7-charts.php" instead of "cf7charts.php")
  • Version: The version number should only use digits and periods (ex. "1.0.3" instead of "1.0 8/1/13...")
  • Description: Please keep the plugin description shorter than 140 characters (currently 278 characters long)
