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
Attributes that need to be fixed:
  • Plugin Name: "Plugin Name" should be replaced with the name of your plugin on the first line ( === activetrail-contact-form-7 === )
The official readme.txt is a good inspiration

activetrail-contact-form-7/activetrail-cfs.php 85% from 13 tests

The main PHP file in "ActiveTrail - Contact Form 7" ver. 1.1.1 adds more information about the plugin and also serves as the entry point for this plugin
It is important to fix the following:
  • Text Domain: Since WordPress version 4.6 the text domain is optional; if specified, it must be the same as the plugin slug
  • Main file name: Name the main plugin file the same as the plugin slug ("activetrail-contact-form-7.php" instead of "activetrail-cfs.php")
