Removing the search form

I tried both the Disable Search plugin, and the code at https://www.wpbeginner.com/wp-tutorials/how-to-disable-the-search-feature-in-wordpress/ with Code Snippets.

Hello,

Tried checking and getting only one search form, and that is the same which you want to use the bb search form

Is your issue fixed?

Thank you, Abhishek. When you say checking, do mean that you looked at my site, or that you tested (at a different site) the plugin or code that I mentioned? When I go to my site, I still see two search forms. The form that I want to remove is to the left of the login form.

Hello,

Seems I misunderstand the issue, I apologize for that.
?Please try to add the below CSS code from the Appearance > Customize > Custom CSS, and check.

#bbpress-forums .bbp-search-form {
    display: none;
}

Thank you so so so much.

You are most welcome ??
