We are running WordPress 4.7.3 with bbpress 2.5.12 at http://one-name.org. This mysql error started appearing last night when accessing any forum, topic or reply. I believe it relates to the ‘AND ((()))’ clause:

Hi, i have the same error after only updating wordpress, not bbpress. Any solution to this ?
SQL is triggered in bbp_has_replies in wp-content/plugins/bbpress/includes/replies/template.php but it has not changed.

Ok, i have something that seems to work, try it out if you want to, feel free to give me feedback on it.

function fix_default_search_string_is_bool($args)
{
    //bbpress gives FALSE as search string causing no replys to show, this fixes it.
    if ($args['s'] === false) {
        unset($args['s']);
    }
    return $args;
}

add_filter('bbp_after_has_replies_parse_args', 'fix_default_search_string_is_bool');
