There is a wide variety of error messages. Here, I am enlisting a few of them which are a bit more common.


  • What are “Warnings” in the WordPress theme check plugin? : You may come across warnings such as “Wrong Directory for same theme name”, “Short tags” etc. These messages are displayed generally if there is something that is not allowed or is unnecessary in the back-end code of your theme.
  • What are “Recommendations” in this plugin? : Recommendations by WordPress theme check Plugin are not as serious as the warnings. Some of the common recommendations that you might see can be related to tags, translation functions, etc. Following the recommendations and you’ll end up with a perfect WordPress compliance.

A theme that you designed keeping your personal preferences in mind may not pass through this plugin.
