Цитата: shpirusА как исправить ошибки в MySQL?Пробуй примерно так:/engine/forum/action/addpost.phpнайти$all_subscr = $db->query(\"SELECT name, email FROM \". PREFIX .\"_forum_subscription AS t1 INNER JOIN \". PREFIX .\"_users AS t2 ON t1.user_id = t2.user_id WHERE t1.topic_id = $topic_id and t1.user_id != {$member_id[\'user_id\']}\");Заменить на:$all_subscr = $db->query(\"SELECT name, email FROM \". PREFIX .\"_forum_subscription AS t1 INNER JOIN \". PREFIX .\"_users AS t2 ON t1.user_id = t2.user_id WHERE t1.topic_id = $topic_id and t1.user_id != \'{$member_id[\'user_id\']}\'\");
