How to delete the text under the reply box

Depends on your theme/site — can you post a link to it?

This is one of my page of my web:

https://www.elsmakeup.com/in-process/

the theme is called “Delicate”
please help, thanks!

The easiest way to do that is in the CSS code with this:

#respond .form-allowed-tags {
   display: none;
}

However, you should use a Child Theme or custom CSS option or plug-in to make any changes to your theme. That way your changes won’t get overwritten when the theme is updated.

Thanks a lot!
