Optimizations

Plugin configuration 90% from 29 tests

readme.txt 94% 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 your attention:
  • Screenshots: Screenshot #1 (No screenshots at the moment.) image missing
The official readme.txt is a good inspiration

pcf-contact-form/contact-form.php 85% from 13 tests

"PCF Contact Form" version 1.2.1's main PHP file describes plugin functionality and also serves as the entry point to any WordPress functionality
It is important to fix the following:
  • Domain Path: The domain path folder does not exist ("/languages")
  • Main file name: The principal plugin file should be the same as the plugin slug ("pcf-contact-form.php" instead of "contact-form.php")
