I am using WordPress-bbpress at the my site.
When many messages were contributed to a topic and it became 10 pages or more, the link to 10th page had broken.

The following code is the cause.
It will replace from “&paged=10” to “0”.

bbpress.2.5.3
C:\xampp\htdocs\bb\wp-content\plugins\bbpress\includes\topics\template.php
895 line

// Remove first page from pagination
if ( $wp_rewrite->using_permalinks() ) {
	$pagination_links = str_replace( $wp_rewrite->pagination_base . '/1/', '', $pagination_links );
} else {
	$pagination_links = str_replace( '&paged=1', '', $pagination_links );
}

One solution for correcting this is the following. (Insert “if($pagination[‘total’] == 1)”)

// Remove first page from pagination
if ( $wp_rewrite->using_permalinks() ) {
	$pagination_links = str_replace( $wp_rewrite->pagination_base . '/1/', '', $pagination_links );
} else if($pagination['total'] == 1) {
	$pagination_links = str_replace( '&paged=1', '', $pagination_links );
}

There was the same code also as the following php file.
wp-content\plugins\bbpress\includes\replies\template.php
wp-content\plugins\bbpress\includes\search\template.php
