Below is a list of my “Do’s & Don’t’s as a WordPress beginner.
Create Custom Plugin – where custom functions will reside. Don’t mess the functions.php file.
Test the plugin – after installing it. Deactivate-delete it if not needed.
Template “Reset” – only when I really need to redo my entire page or post template. If “Reset”, back-up the template components so I can copy if in case I will need them.
