How to bypass a theme editor block?

Question

I have downloaded a theme but would like to edit the PHP files, but there is a theme editor block. I can't access it by typing the theme editor into the url, I just wondered if there is a way of getting around it.

Answer 1

It is highly discouraged to edit themes like that, because any changes made that way will be deleted upon update. The recommended way is to create a child theme and edit your PHP CSS and HTML there.

By using a child theme you will ensure that your modifications are preserved. Using a child theme can speed up development time. Using a child theme is a great way to learn about WordPress theme development.

all the documentation to create a child theme is here Wordpress Codex

Answer 2

You will have to open functions.php for that theme outside of wp-admin. Like in a text editor or ide and upload it back to your themes folder.
