    • > PHP Fatal error
      Uncaught Error: Class 'WP_Customize_Control' not found in wp-content/plugins/advanced-css-editor/syntax-highlighter.php:3
    • > PHP Fatal error
      Uncaught Error: Class 'WP_Customize_Control' not found in wp-content/plugins/advanced-css-editor/layout-picker.php:3

      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/advanced-css-editor/css-editor.php:126

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)
Everything seems fine, but this is not an exhaustive test


Plugin configuration 87% from 29 tests

readme.txt 88% from 16 tests

The readme.txt file uses markdown syntax to describe your plugin to the world
Attributes that need to be fixed:
  • Tags: Please delete some tags, you are using 12 tag instead of maximum 10
  • Screenshots: These screenshots do not have images: #1 (Screenshot 1. Add a global custom CSS), #2 (Screenshot 2. Add custom CSS for Desktop), #3 (Screenshot 3. Add custom CSS for Tablet), #4 (Screenshot 4. Add custom CSS for Phone)
The official readme.txt is a good inspiration

advanced-css-editor/css-editor.php 85% from 13 tests

"Advanced CSS Editor" version 3.1's main PHP file describes plugin functionality and also serves as the entry point to any WordPress functionality
You should first fix the following items:
  • Main file name: Even though not officially enforced, the main plugin file should be the same as the plugin slug ("advanced-css-editor.php" instead of "css-editor.php")
  • Description: If Twitter did it, so should we! Keep the description under 140 characters (currently 147 characters long)
