remove url field from comments form

Hi there,

Give this a shot:
https://docs.generatepress.com/article/remove-e-mail-and-url-field-from-comment-form/

Please also make sure you are using the latest versions of the free theme and premium plugin:
https://docs.generatepress.com/article/generatepress-and-gp-premium/

Let me know if this helps :)

Where should the php be placed? It is not clear where the code goes.

Did you click on the PHP link in this sentence in the article?

Then add the PHP snippet below to remove the field

The same link is also at the bottom of the article.

Let me know :)

I really don't want another plugin. I asked if there was a way to do it within theme files or css in my original post.

Child theme is the only other option if you don't want to use Code Snippets:
