np-forex-commodity-widget/nfcw-commodity-widget.php 69% from 13 tests

The main PHP file in "NP Forex Commodity Widget" ver. 1.6 adds more information about the plugin and also serves as the entry point for this plugin
It is important to fix the following:
  • Text Domain: The text domain is optional since WordPress version 4.6; if you do specify it, it must be the same as the plugin slug
  • Main file name: Name the main plugin file the same as the plugin slug ("np-forex-commodity-widget.php" instead of "nfcw-commodity-widget.php")
  • Domain Path: The domain path points to an invalid folder, "/languages" does not exist
  • Description: Keep the plugin description shorter than 140 characters (currently 156 characters long)
