Hello

I am working on my local server, and the folder name for my WordPress is “custom_theme.” I am currently testing the following code. However, it is not functioning as expected. When I add a lesson, like “simple lesson,” the resulting URL is https://localhost/custom_theme/simple-lesson/, leading to a 404 error.

I am trying to figure out why it is not working as intended. Could you please assist me in understanding the reason behind this issue? Additionally, if I choose a category, such as “California,” the expected URL should be https://localhost/custom_theme/california/simple-lesson/.
