Plugin configuration 86% from 29 tests

readme.txt 94% from 16 tests

The readme.txt file is an important file in your plugin as it is parsed by WordPress.org to prepare the public listing of your plugin
Attributes that require attention:
  • Tags: Too many tags (44 tag instead of maximum 10); only the first 5 tags are used in your directory listing
You can look at the official readme.txt

advanced-product-labels-for-woocommerce/woocommerce-advanced-products-labels.php 77% from 13 tests

The main file in "Advanced Product Labels for WooCommerce" v. serves as a complement to information provided in readme.txt and as the entry point to the plugin
You should first fix the following items:
  • Text Domain: Please use dashes and lowercase characters for text domains
  • Main file name: Even though not officially enforced, the main plugin file should be the same as the plugin slug ("advanced-product-labels-for-woocommerce.php" instead of "woocommerce-advanced-products-labels.php")
  • Domain Path: The domain path is invalid: folder "/languages/" does not exist
