I will say though that this is a common issue with bbPress and BuddyPress when it comes to SEO tools. They need to find a way to get proper meta descriptions and titles without borking everything :p
I was the same on my site, google searching I found this, I do not remember where I found it but works.
You must add the following to functions.php of your chil theme, for the title:
//Titulo bbpress
add_filter( ‘aioseop_title’, ‘packeteater_bbpress_forum_title’ );
function packeteater_bbpress_forum_title( $title ) {
if ( is_post_type_archive( ‘forum’ ) ) {
$title = “Your forum tittle”;
}
return $title;
}
And for the description:
//Descripcion bbpress
add_filter( ‘aioseop_description’, ‘packeteater_bbpress_forum_description’ );
function packeteater_bbpress_forum_description( $description ) {
if ( is_post_type_archive( ‘forum’ ) ) {
$description = “Your forum description”;
}
return $description;
}
I hope it helps you
