maybe it’s bb-attachment plugin??

line 97

// insane bbPress workaround – adds multipart enctype to the new post form via uri patch

function bb_attachments_enctype() {add_filter( ‘bb_get_option_uri’,’bb_attachments_uri’,999);}

function bb_attachments_uri($uri) {remove_filter( ‘bb_get_option_uri’,’bb_attachments_uri’,999);

return $uri. ‘bb-post.php” enctype=”multipart/form-data” hack=”‘;}

let me contact the maker.
