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 is undoubtedly the most important file in your plugin, preparing it for public listing on WordPress.org
Attributes that require attention:
  • Screenshots: Add images for these screenshots: #1 (Simple Admin Interface), #2 (Advanced Admin Interface), #3 (Default Splash Page)
  • Tags: Too many tags (25 tag instead of maximum 10); only the first 5 tags are used in your directory listing
The official readme.txt might help

browser-blocker/browser_blocker.php 85% from 13 tests

The main PHP file in "Browser Blocker" ver. 0.5.6 adds more information about the plugin and also serves as the entry point for this plugin
The following require your attention:
  • Description: If Twitter did it, so should we! Keep the description under 140 characters (currently 273 characters long)
  • Main file name: Even though not officially enforced, the main plugin file should be the same as the plugin slug ("browser-blocker.php" instead of "browser_blocker.php")
