Optimizations

Plugin configuration 90% from 29 tests

readme.txt 94% from 16 tests

The readme.txt file is important because it is parsed by WordPress.org for the public listing of your plugin
These attributes need to be fixed:
  • Tags: Please delete some tags, you are using 32 tag instead of maximum 10
The official readme.txt might help

addfreestats/addfreestats.php 85% from 13 tests

The entry point to "AFS Analytics" version 4.14 is a PHP file that has certain tags in its header comment area
Please take the time to fix the following:
  • Requires at least: Required version must match the one declared in readme.txt ("3.5.0" instead of "1.4.1")
  • Text Domain: You no longer need to specify the text domain since WordPress 4.6; it must be the same as the plugin slug
