Plugin configuration 90% from 29 tests

readme.txt 88% from 16 tests

You should put a lot of thought into formatting readme.txt as it is used by WordPress.org to prepare the public listing of your plugin
These attributes need to be fixed:
  • Screenshots: Add images for these screenshots: #7 (Shortcode output.), #8 (Widget output.)
  • Tags: You are using too many tags: 17 tag instead of maximum 10
You can take inspiration from this readme.txt

accredible-certificates/accredible_certificates.php 92% from 13 tests

"Accredible Certificates & Open Badges" version 1.4.8's primary PHP file adds more information about the plugin and serves as the entry point for WordPress
Please make the necessary changes and fix the following:
  • Main file name: Please rename the main PHP file in this plugin to the plugin slug ("accredible-certificates.php" instead of "accredible_certificates.php")
