bbPress.org

yes, drop this into your functions file.

This will send users to the /forums/ page whenever they log out -whether private or public forum or on a topic or reply, or anywhere within bbpress. If you logout, you’re saying your done, so taking you back to the index seems a logical place to end up !

You can change the $url to say ‘/home/’ if you want the home page,

//sends the user to $url - in this case '/forums/'  
function rw_logout ($redirect_to) {
	$url='/forums/' ;
	$redirect_to = '<a href="' . wp_logout_url( $url ) . '" class="button logout-link">' . esc_html__( 'Log Out', 'bbpress' ) . '</a>' ;
	return $redirect_to ;
	}
	
	add_filter ('bbp_get_logout_link', 'rw_logout') ;
	

no the file is one that belongs to your theme called just functions.php

you’ll find it at

wp-content/themes/%yourthemename%/functions.php

where %yourthemename% is the name of your theme.

If you don’t have a child theme, then you should create one, see

great – glad you’re fixed !
