Optimizations

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:
  • Tags: There are too many tags (25 tag instead of maximum 10)
  • Screenshots: No descriptions were found for these screenshots #1, #2, #3, #4 in prolike-button/assets to your readme.txt
The official readme.txt might help

prolike-button/index.php 92% from 13 tests

"Pro Like Button" version 1.0.4's primary PHP file adds more information about the plugin and serves as the entry point for WordPress
Please take the time to fix the following:
  • Main file name: Please rename the main PHP file in this plugin to the plugin slug ("prolike-button.php" instead of "index.php")
