Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

Often overlooked, readme.txt is one of the most important files in your plugin
Attributes that need to be fixed:
  • Tags: You are using too many tags: 13 tag instead of maximum 10
Please take inspiration from this readme.txt

8-degree-notification-bar/8degree-notification.php 85% from 13 tests

"Notification Bar for WordPress" version 1.1.8's primary PHP file adds more information about the plugin and serves as the entry point for WordPress
You should first fix the following items:
  • Main file name: The principal plugin file should be the same as the plugin slug ("8-degree-notification-bar.php" instead of "8degree-notification.php")
  • Text Domain: The text domain is optional since WordPress version 4.6; if you do specify it, it must be the same as the plugin slug
