Delete a URL field (site) from a comment form

Hello!

Thank you for updating the theme, but I have a problem – please help.

I need to remove the “site” field from the comment form – once I did it, thanks to a simple solution that was suggested to me here:
https://www.ads-software.com/support/topic/how-to-delete-a-url-field-site-from-a-comment-form/

Through CSS styles:
.comment-form-url input#url {
display: none;
}

But now, after updating the theme to version 1.33 and WordPress to version 5.0.3. the solution stopped working correctly: the word “site” is visible, although there is no input field (here is an example, read: blog.andrewbondar.ru/etika-fotografa/)

Please tell me a new solution!
