    • > PHP Fatal error
      Uncaught Error: Call to undefined function __() in wp-content/plugins/2kb-performance/admin-template.php:1

Plugin configuration 90% from 29 tests

readme.txt 88% from 16 tests

Don't ignore readme.txt as it is the file that instructs WordPress.org on how to present your plugin to the world
These attributes need to be fixed:
  • Contributors: Plugin contributors not specified
  • Plugin Name: Write the name of your plugin instead of "Plugin Name" on the first line ( === 2kb-performance === )
The official readme.txt is a good inspiration

2kb-performance/plugin.php 92% from 13 tests

"2kb Performance" version 1.1.0's main PHP file describes plugin functionality and also serves as the entry point to any WordPress functionality
It is important to fix the following:
  • Main file name: Even though not officially enforced, the main plugin file should be the same as the plugin slug ("2kb-performance.php" instead of "plugin.php")
