Registered sidebar not showing in WordPress widgets (Theme development)

May 15, 2018

Hey Developer,

If you are just starting out with WordPress and you want to create your own theme, you may have ran into this same problem that I did. All I wanted to do is register my first sidebar in functions.php. I went on to look at the
official documentation and I missed a very important piece of the puzzle.

I just copied and pasted the code and modified some of the parameters such as id but I failed to realize that I should not use uppercase letters. Afterwards, I spent hours trying to figure out why my sidebar was not working and I am hoping to help you avoid the same problem.
